Gaga goes nude and more fashion news!

Welcome to the weekly fashion round-up, where we bring you the latest on supermodels, style, designers and everything in-between!

Which supermodel came clean about her addictions? Which celeb's dress is a sell-out?

Here's the lowdown on the latest fashion news!

Katy Perry hated her curves as a youngster, wanted to look like Kate Moss

Singer Katy Perry has admitted that she used to lament having big breasts, but now they've "come in handy".

"I was shaped like a square at one time. I was!" the New York Daily News quoted her as telling Elle magazine.

"I'm generally around 130 pounds, which is totally fine for me."

"But when I was a kid, I was the same height and weighed more like 145."

"And I had enormous boobs that I didn't know what to do with, so I wore minimisers, which were not cute. Those thick-ass straps! I got made fun of for the over-the-shoulder boulder holder...and all I wanted was to look like Kate Moss."

"Little did I know...that these things would come in handy someday," the 26-year-old said.

Still, Perry told the magazine that she believes "it's important to be relatable and normal."

"And I think that what helps with that, for me, is that I had the rug pulled out from underneath my feet so many times," the singer said.

"It was like, 'Listen up, b----, you're not going to get served this on a silver platter -- you've got to work for it!' I don''t feel like I can act like an entitled b---- yet! I still have so much to prove," she added.

Lady Gaga has reportedly posed nude with a skateboard as part of a new ad campaign.

The Bad Romance singer has stripped for her starring role in a new ad campaign for Supreme Skateboards, reports the Daily Telegraph, wearing nothing aside from a pair of shades, a conveniently placed skateboard and bizarre vertiginous heels.

Known for her eccentric fashion sense, Gaga is also coming up with a new perfume that smells of 'blood, sweat and semen'.

The 24-year-old pop star has signed a lucrative deal with perfume company Coty, reports the Daily Star.

And she has ordered the makers to base the scent on bodily fluids.

However, fans will have to wait until next spring to get a whiff of it.

She may have landed in a legal soup again, but Lindsay Lohan's sexy, all-white, form-fitting, mid-thigh dress, which she wore to court, has been selling like hot cakes.

The dress from designer Kimberly Ovitz's pre-fall collection is selling out at online stores that carry it, ABCNews.com reported.

The dress retails for 575 dollars. Some brick-and-mortar retailers may still have it, reports the New York Post.

The moment the Mean Girls star stepped out of a black SUV in front of the LA courthouse, attention shifted to her dress.

On her Twitter account, Lohan wrote, "i would never steal, in case people are wondering. I was not raised to lie, cheat, or steal... also, what i wear to court shouldnt be front page news. it's just absurd."

Like Lindsay, Naomi Campbell also found it hard to cope with the pressures of celebrity in her younger days. In an interview, the supermodel has confessed that she used drink and drugs to "numb" the suffering that followed her sudden rise to fame.

The London-born lass also admitted that she was an "active addict" during her twenties -- meaning she partied hard but wasn't confined to bed the following day.

However, Campbell steers clear of mind-altering substances these days, recognising they ended up exacerbating her problems.

"It rips your world apart. I never thought I was an alcoholic but it goes hand in hand with the drugs," the Sun quoted her as telling GQ.

"Emotionally I was just gone. I was emotionally unattached to myself."

"You just want to numb your pain. And I've got tons of stuff. Same as everybody else. I didn't like the way I was."

"Drink and drugs are an allergy for me, and they don't make me a better person."

The supermodel claimed she was a late bloomer on the social scene, and took full advantage once the modelling cash began to roll in.

She continued: "I was a party girl. I started quite late, 24. I was having fun. It wasn't that I couldn't get out of bed in the morning without it. It wasn't a coping mechanism. It was a party thing and I didn't realise how powerful it was, in a very wrong way."

"The fun comes with consequences. You are killing yourself...I was an active addict. But I could still function," she added.

Pregnant Victoria Beckham has dismissed rumours that she will pose nude for US Vogue magazine.

It was previously reported that the 36-year-old was set to pose 'Demi Moore style' for the cover of the US style bible, reports the Telegraph.

The reports claimed that editor-in-chief Anna Wintour was keen to depict Beckham at seven months pregnant with her fourth child.

However, Victoria's people have now denied the rumours, refusing to give any further comment on the claims.

TV viewers have lashed out at Elizabeth Hurley for mocking environmental issues in a new commercial.

The glamorous British actress appears in a multi-million pound ad campaign for US discount firm Groupon, in which she compares the loss of rainforests to a cut-price Brazilian bikini wax, reports the Sun.

In a tongue-in-cheek ad, which aired in the US during Sunday's Super Bowl game, the Austin Powers star called Brazil''s rainforest 'one of nature's most lush ecosystems'.

She then added 'not all deforestation is bad!' and revealed she saved 50 percent on her Brazilian wax because of a group discount.

Angry viewers claimed Hurley's clip makes light of serious environmental matters.

"I look forward to a Groupon campaign for roadside assistance using Egypt. That'd be droll! These ads are reprehensible," said one TV critic.

Online viewers lashed out on Twitter.

Supermodel Gisele Bunchen's representatives have set the record straight after she allegedly described sunscreens as "poison."

They insist that the Brazilian beauty didn't mean to appall the dermatologists of the world when she made the remark, reports the New York Daily News.

"I cannot put this poison on my skin," the 30-year-old had said at the Sao Paolo launch of her own organic skin care line. "I do not use anything synthetic."

"Gisele would never say not to use sunscreen because she has had family members who have had skin cancer," her publicist Amber Clapp told StyleList.

"She simply stated that her all-natural skin-care line does not have SPF because there is not an all-natural SPF available."

Her rep was quick to point out that Gisele does use sunscreen -- just not the ones that contain "parabens, oxybenzone, PABA and retinyl palmitate."

Another supermodel mom who's had to defend herself this week is Miranda Kerr.

The Aussie supermodel caused a stir when she posted a snap taken by husband Orlando Bloom, of her breastfeeding newborn son Flynn, on her blog. And now she has explained her decision, reports News.com.au

Miranda said that she was only promoting breastfeeding, and encouraging mothers to not be put off by stigmas that might be attached to feeding babies in public.

"To me it is the most natural thing in the world and I love it and the bonding time we have during these precious and beautiful moments," she said.

"Honestly, I for one can say there are more breasts being shown on a daily basis around the world in swimwear and low-cut dresses and tops than there are from breast-feeding mums," she added.

Kim Kardashian says she now loves the naked images taken of her in W magazine.

She had initially described the images as "porn", and claimed the magazine had gone back on its word by not covering her with pictures of artwork.

Appearing on the cover of the edition dubbed 'The Art Issue', Kardashian appears fully naked with only strategically placed text preserving her modesty, reports the Sydney Morning Herald.

Inside the magazine, the super-imposed text is removed and Kardashian is shown in all her glory.

Speaking to Us Magazine on Friday, she said she now regarded the photographs as "beautiful".

"Obviously I'm comfortable posing nude -- I've done that before, and I did that then for the magazine -- but that's probably not the direction I would've wanted to go if I thought that was going to be the case," she said.

"Looking back, I love the photos. W magazine is iconic, so I'm really happy that I did it and that those are the phots," she added.

For her most recent magazine shoot, however, the curvy reality star has kept her clothes on -- and recreated Elizabeth Taylor's famous interpretation of Egyptian queen Cleopatra.

Kardashian did a photoshoot for Harper's Bazaar in an animal print dress, reports the Daily Mail.

The 30-year-old posed reclining on a sofa, showing off her shapely figure.

But in the accompanying interview, Kim admits keeping her figure that trim does not come naturally.

"I'm on a diet. I need to be. I love to eat -- Kit Kats or cookies-and-cream ice cream. I need sugar like five times a day," she said.

World-renowned burlesque dancer Dita Von Teese has raised eyebrows playing a stripper in the racy new TV advertisement for Renault Clio.

The glitzy commercial also co-stars Rihanna and French footballer Thierry Henry, reports the Daily Mail.

The ad, which Renault is calling its 'Va Va Voom' commercial, opens with a star-studded montage featuring Audrey Hepburn in a clip from Breakfast at Tiffany's, the late Marlon Brando and David Bowie.

Dita then emerges and begins to strip off as Thierry, who plays a strip club regular, ogles her by peeping through a glory hole.

Dita removes her corset and bra and is topless while Thierry marvels at her assets.

Rihanna then flashes on screen, inter cut with a clip of Marlon Brandon speaking the famous line "I coulda been a contender" from the 1954 film On the Waterfront.

Finally after all the skin and the superstars have left the screen, several shops of the car pop up.

Renault has unveiled its sexy new campaign on ITV.

Singer and actress Jennifer Hudson still hasn't come to terms with the fact that she has shed those extra pounds.

"I go into the store, and they try to put me in 4s and 6s, and I'm like, "Who are you trying to talk to?" the 29-year-old star told PeopleStylewatch, "My mind hasn't caught up yet."

"I didn't expect to go as far as I did," she said.

The Oscar-winning star was a size 16 before she became the spokesperson for Weight Watchers last year, reports the New York Daily News.

"Everyone sees the new Jennifer, but I'm stuck in my mind with the old one," she told USA Today in January.

Singer Joss Stone has posed naked in a PETA ad to protest against the UK's Ministry of Defence killing bears to use their fur for hats.

Regiments of the Queen's Guards including the Scots Guards and the Coldstream Guards wear bearskin hats, made from the North American black bear.

Stone, 23, is seen holding a teddy bear that covers up most of her naked body, with the slogan "Bear Hugs, Not Bear Caps" in the background.

"Too many people at the Ministry of Defence are dragging their heels on this issue, and I feel like more needs to be done to stop the murder," the Daily Mail quoted Stone as saying.

"It's time for the Ministry of Defence to finally make the switch and go fur-free, and I hope that the ad I have created with PETA helps raise awareness and puts a stop to this unnecessary killing," she added.

Animal welfare group PETA are campaigning against the killing of the bears for the hats, but a MoD spokesperson has defended the military's decision to kill bears.

"The North American Black Bear, whose fur is used, is not killed specifically for the Footguards' caps," the spokesperson said.

"Their numbers in the USA and Canada are kept under control through very strictly enforced licensing regimes -- this is how the fur is sourced."

"We have looked into alternative man-made materials in the past, but none has come remotely close to matching the natural properties that bear fur possesses."

"We would be very happy to work with any potential supplier who believes they have the answer," the spokesperson added.

Now who wouldn't want a romantic celebration with this hottie?

Irina Shayk, the Russian model girlfriend of Portuguese soccer star, Cristiano Ronaldo, seems to be gearing up for Valentine's Day.

While Shayk was in Istanbul to walk in a runway show for fashion line Damat, she picked him up a Valentine's Day card written in Turkish, reports the New York Post.

According to reports, though there is no word on what the card reads, Shayk had it translated.

The 25-year-old beauty shared the catwalk with Dita Von Teese, who was in Istanbul with her beau, French actor Louis-Marie de Castelbajac.
