Jenny McCarthy bares all for Playboy

Jenny McCarthy has posed in the buff save for fishnet gloves, knee-highs and red-hot nail lacquer for the latest issue of Playboy Magazine.

The 39-year-old actress and comedian said that she was very proud of the way the shoot turned out.

"I'm really proud of it. See, proud," the Mirror quoted her as telling People Magazine.

"The pictures are really gorgeous and classy. They could be out of W Magazine. They're really elegant. It's probably a lot more sophisticated than a lot of the stuff you'd see of people with their clothes on," she said.

The mother of one, who is dating Chicago Bears linebacker Brian Urlacher, began her career as a Playboy model in 1993.

"The one thing I like about Playboy is they don't have the anorexic look. The women are voluptuous. So I didn't really want to diet, I just wanted to tone up," she added.

Kim Kardashian has revealed that she is unhappy with her thighs and wears spanx to look slimmer.

Although the 31-year-old socialite is body-confident, she admits there are things she doesn't like about her physical appearance because she is a perfectionist.

"I'm such a perfectionist that I'm not really completely happy with my body. I don't like my thighs, I wear spanx a lot, they're like the greatest invention," Contactmusic quoted her as saying on UK TV show Lorraine.

"I like to do a little QuickTrim cleanse before bikini time and photo shoots and if I've got something coming up I don't eat as bad and I work out all the time," she said.

Kim also revealed that she has a spray tan every 10 days, as she likes to maintain her sun-kissed glow.

"I have a spray tan every 10 days -- I know I do it a lot, but I love it," Contactmusic quoted her as telling Now Magazine.

"I have a guy called Jimmy Coco come to my house in LA and spray me. I don't know what fake tan he uses, but he's a great tanner," she said.

The Keeping Up with the Kardashians star also admits she relies on fake tan when she has a break-out of psoriasis, a painful dry skin condition.

"My psoriasis is flared up right now. It's really bad and it's annoying. I'm using Sally Hansen Airbrush Legs which is a wash-off tan and is the only thing that works for me, as it really covers it up."

"My psoriasis doesn't stop me going out, but I don't know what to do about it -- I need help," she said.

While Kim likes to tan regularly, she admits she doesn't wash her hair very often.

"I try to avoid washing my hair a lot. I love to use Moroccan Oil to give it all a really great shine," she said.

Argentinian actress Luisana Lupilato looks positively stunning in a new campaign for lingerie giant Ultimo.

The 24-year-old blonde beauty, who is married to singer Michael Buble, puts her amazing curves on display in a luxurious satin bra with a diamante back strap and lace knickers.

Ultimo founder and CEO Michelle Mone is thrilled that Luisana signed up with the brand last year -- she claims that sales have rocketed a staggering 37 per cent since, according to the Daily Mail.

"Luisana is one of our biggest international stars and the response we have had has been phenomenal," she was quoted as saying.

Katy Perry has revealed that she sometimes feels she has a split personality and said that her eccentric dress sense represents her conflicting emotions.

The Firework hitmaker admits her outrageous outfit choices reflect her moods at the time, saying that is why her creations are sometimes bizarre -- because she feels a mixture of emotions.

"My sense of style is like one of those things that change colour with mood, always evolving," Contactmusic quoted her as telling L'Uomo Vogue Magazine.

"When I get up, I choose my outfit depending on my state of mind. If it is a 'mixture of many things' it is because I feel many different emotions at the same time, to the point where you feel you almost have a split personality."

"Basically, in the past, my preferences were always directed towards styles that were d#229 the flashier, shinier and imposing the dress the better. This is the reason why I still love the work of Jean Charles de Castelbajac and Jeremy Scott," she said.

Shobna Gulati, whose character in Coronation Street was transformed from dowdy shop assistant to sexy mistress, has been named the Rear Of The Year.

The soap star has been awarded the title along with Torchwood actor John Barrowman.

Barrowman and the 45-year-old actress were named the winners of Wizard Jeans Rear Of The Year, on Wednesday.

At the unveiling of this year's honorees, the actors joined forces to show off their bottoms in a cheeky photoshoot at London's Dorcester Hotel.

Clearly having fun with their new titles, the pair even enjoyed a cheeky grope of each other's bottoms.

"I am really honoured and flattered to be a winner of this year's competition and for my bum to be etched into the history of the award's alumni -- a list which includes so many other distinguished bottoms," the Daily Mail quoted her as saying.

"And I'd also like to say thanks -- in the words of Will.i.am, 'I got it from my mama,'" she said.

West End star Barrowman, also 45, said that he was thrilled to receive the award.

"With tush tightly toned, cheeks firmly clenched and a big smile on my face, I'm thrilled to be awarded the accolade," he said.

Last year's title went to Loose Women presenter Carol Vorderman and Strictly Come Dancing professional Anton Du Beke.

Sally Allen, of sponsor Wizard Jeans, called the winners 'two excellent examples of this year's ideal rear'.

"Shobna's slim but womanly silhouette is a fine example of the happy, healthy female form for 2012 and John's rear is clearly admired on an international basis, judging by the number of fans who voted for him. No doubt his dancing prowess helps to keep him in tremendous shape," Allen added.

Previous winners of the Rear Of The Year Awards include Charlotte Church, Denise Van Outen, Fiona Bruce and Jennifer Ellison.

Mila Kunis, who's considered one of the sexiest women in the world, has claimed that her unique sense of humour may be the reason why men fall for her.

The Black Swan star said that she has noticed she's consistently the only girl on set in her movies, but doesn't think this has anything to do with her looks.

"I do a lot of movies with a lot of guys, for some reason," the Daily Express quoted her as saying.

"There's an aspect of my humour I guess is very guy-friendly, but I do believe that I'm still feminine. I like to hold that for all the ladies!" she said.

Jessica Simpson has said that American-based international company Weight Watchers is not pressurising her to lose the baby weight that she gained while she was pregnant.

Since giving birth to her daughter Maxwell Drew in May this year, the 31-year-old singer has become a constant fixture at the gym.

According to initial reports from In Touch Weekly, Simpson had been 'stressed and overwhelmed' by the four million dollar deal that she had signed with the diet company to shed 50 pounds in five months.

But the new mom insisted that she is not feeling pressure to lose the baby weight quickly.

"Just so everyone knows, Weight Watchers hasn't put ANY pressure on me!" the New York Daily News quoted Simpson as writing on Twitter.

"I'm trying to be as healthy as I can for myself and I feel great," she wrote.

However, the singer who has been engaged Eric Johnson since fall 2010, admitted her desire to return to her old shape.

Salvatore Ferragamo has released a first look at its fall/winter 2012 advertising campaign starring Kate Moss.

The British supermodel is her usual photogenic self in the images shot by Mikael Jansson, who has also worked for the likes of Dior and Chloe, the Daily Mail reports.

Shot in Berlin's prestigious Russian embassy, the 38-year-old blonde beauty is seen posing nonchalantly in several creations from Ferragamo's latest collection. Co-starring in the campaign alongside Kate are models Karmen Pedaru and Sean O'Pry.

In a statement from for the Italian fashion house, the images are described as "a role-play between Kate Moss's unmistakable femininity, Karmen Pedaru's reserved beauty and Sean O'Pry's striking appeal, amidst a geometrical play of mirrors and fabrics that recreates the environ of a fairy tale palace...Kate, naturally vibrant yet sophisticated, perfectly interprets the essence of this Autumn/Winter collection."

Lady Gaga, who made headlines for her controversial meat dress, has upgraded her wardrobe by paying a world record price for a gown by her late friend Alexander McQueen at an auction.

The 26-year-old singer is said to have set a new high for a McQueen, bidding 85,250 pounds in a sale which saw her facing rival bids from institutions and couture collectors from all around the world.

She was among bidders from 21 countries, who paid almost half a million pounds for items from the personal collection of Daphne Guinness which was sold at Christie's, the Daily Mail reported.

Christie's confirmed that Gaga was a bidder but was unable to provide any further details of the items that she had purchased.
