Jennifer Aniston, ex-hubby Brad Pitt voted hottest-bodied celebs

Actress Jennifer Aniston along with her ex- hubby Brad Pitt has been voted as 'Most Fit Over 40' stars.

Aniston also topped the list for 'Most Wanted Celebrity Body' and 'Most Wanted Celebrity Body Part', beating Halle Berry and Cameron Diaz in the respective categories.

The titles were released by a new celebrity body survey conducted by Fitness Magazine and Yahoo OMG!, US Magazine reports.

The 47-year-old actor's partner Angelina Jolie was absent from the categories, which also include 'Best Body After Baby' (Jennifer Lopez) and 'Hottest Celeb Couple' (David and Victoria Beckham).

Canadian singer Michael Buble's wife Luisana Lopilato has been unveiled as the new face of lingerie giant Ultimo.

The Argentinian actress has been chosen to front the brand's latest autumn/winter 2011 campaign, which features underwear designed to enhance the cleavage and create 'the perfect silhouette'.

Wearing structured pieces from the Ultimo Miracle collection, Lopilato demonstrates the shaping properties of the collection, from plunge-neck body suits to strapless bras and diamante-embellished pieces.

"Luisana is one of our most exciting international signings yet and I'm confident she'll bring a new sense of fun and glamour to the brand as our incredible face and body," the Daily Mail quoted Ultimo founder and CEO Michelle Mone as saying.

"It took me a long time to get her but I refused to give up until I got her. Luisana's jaw-dropping beauty and charisma are a perfect fit for Ultimo and we can't wait to unveil our new designs," she added.

Lindsay Lohan decided to go nude for Playboy because she was extremely concerned about her financial situation if she was given a possible jail sentence.

Lohan, 25, earned one million dollars for posing naked for the magazine.

"Lindsay still hasn't signed her contract to be in the John Gotti biopic. Lindsay is extremely concerned about her finances, and she needs the money," a source told Radar Online.

"Lindsay's flow of income has been greatly diminished in the last year. With the possibility of being sent back to jail for over a year, she felt that now was the time to do the Playboy photoshoot," the source added.

The Mean Girls star has been ordered to complete 16 hours per week at a morgue before her probation violation hearing on November 2, which could possibly sentence the actress to 18 months in jail.

Actress Denise Richards regrets her decision of undergoing breast enhancement surgery as a teenager, and is worried that she sends a "confusing message" to her young daughters about body image by fussing over her looks.

The former Bond girl was only 19 when she went under the knife to enhance her bust, but now she is afraid that her decision undermines the advice she gives her little girls about positive self-esteem.

"I often times feel like a hypocrite with my daughters when trying to teach them to have a healthy view on beauty and body image. I'm in a business where looks and weight do matter..." Contactmusic quoted her as writing in her blog on iVillage.com

"My girls see me at work or getting ready for photoshoots and I'm sure at times it can be a confusing message to them when I'm being primped, dressed and fussed over. I always explain it's Mommy's job. They see me get spray-tanned and my nails done too. I always need fresh nails every week..."

"At 19 when I first got my breasts done, I wish that I was confident enough with my body to not have had surgery. That is something that I really want to encourage in my daughters, to embrace their healthy body and have confidence," she added.

The actor has two daughters, Sam, seven, and Lola, six, with ex-husband Charlie Sheen, and she has recently adopted a baby girl called Eloise.

Cheryl Cole has poked fun at Hollywood's obsession with cosmetic surgery by sporting a huge pair of fake lips.

The Girls Aloud star tweeted a snap of herself sporting an inflated plastic pout. "I think we've been in LA too long. LMHO!!" the Daily Star quoted her as posting on her Twitter page.

Earlier this year, she admitted she was baffled by people who have nose jobs. "I can't get my head around everyone having the same nose because it's the unique things about you that make you beautiful," she said.

"I'm not judging, but unless something is really getting you down, it's best not to mess with nature," she added.

Kate Price has spent a whopping 288,000 pounds on hair extensions in the past 12 years.

Price regards the maintenance of these hair extensions as her biggest personal extravagance.

"I have them done every three months and it costs six grand each time," the Daily Star quoted Price as saying.

"I've been doing that for 12 years so that's 288,000 pounds. I also pay 20 pounds four times a year for a short back and sides," she added.

Superstar Kate Winslet has refused to diet and wants young girls to realise that it is possible to have a healthy shape.

The 36-year-old beauty insists that she is not interested in dieting and would rather encourage young girls to have a healthy body image.

"I am not a twig -- and refuse to be a twig. I would like young girls who are screwed up about their bodies to think that it's possible to have a healthy shape. Everyone gets a bit screwed up about themselves, physically, when you're growing up," Contactmusic quoted her as telling Reveal Magazine.

"I don't do crash diets or eat fish rather than meat and salads until they come out of my ears."

However, Kate does work out in order to stay healthy.

"I do exercise, with plenty of swimming, but never feel that I have the figure of a Hollywood actress," she added.

Brides-to-be can now get the desired Pippa or Kate Middleton wedding look at High Street prices.

When Pippa stepped onto the red carpet to pick up sister Kate's train at the royal wedding, her maid-of-honour dress quickly became the most requested in bridal ateliers across the world.

Considering its increasing demand, Debenhams has unveiled a replica of Pippa's 20,000 pound Alexander McQueen gown at just 170 pounds, the Daily Mail reported.

The cowl-neck dress goes on sale at the high street department store, accompanied by a host of other royal wedding-inspired pieces.

"Both men and women everywhere were instantly talking about Pippa, so naturally brides-to-be will want to emulate her classic look -- both for themselves or their bridesmaids," Alain Mehada, chief personal shopper at Debenhams' Oxford Street flagship, said of the collection.

"We have been inundated by customers asking if we have anything similar to the dresses worn by Kate, Pippa and the flower girls, but the ivory dress worn by Pippa is the most requested by far," he stated.

The retailer will also stock a 99 pound version of the emerald green Alice Temperley evening gown Pippa wore to the evening reception at Buckingham Palace.

There is also a black lace sweetheart cocktail-length dress in homage to Kate -- inspired by her magnificent Alexander McQueen wedding gown.

Completing the set is a flower girl dress cinched with wide gold ribbon that echoes that of the bridal party, on sale for just 48 to 52 pounds depending on age.

Salma Hayek has revealed that she was devastated when she was banned from wearing high-heels because of her foot injury.

The 45-year-old Mexican American actress tore two ligaments in her foot last year and as a result was restricted from wearing her beloved stilettos.

"The worst part about it is you can't wear heels. You've never been a Mexican short woman! This is tragic. I often say, had it not been for high heels, I would still be in Coatzacoalcos with 10 kids!" Contactmusic quoted her as saying on The David Letterman Show.

Salma further revealed that the doctors want her to undergo a surgery to correct her foot, but the actress admits that she is scared to do so.

"They want me to have surgery but I'm not keen. I don't like surgery," she added.

Gwyneth Paltrow says that a good night's sleep is vital to look good.

The Oscar-winning actress, who has two children, Apple, seven, and five-year-old Moses with husband Chris Martin, has confessed that if she doesn't take proper rest, it shows on her appearance.

"For me, sleep is a major thing. I don't always get it, and when I don't, I look like I've been hit by a truck," Contactmusic quoted her as saying on Sirius XM Radio.

Gwyneth credits her youthful looks to drinking lots of water, taking vitamins "religiously" and having at least one cup of coffee -- with almond milk -- each morning.

Gwyneth also credits celebrity trainer Tracy Anderson for her amazing figure, though previously she had said that she doesn't like to diet and eats what she likes because she exercises so much.

"I had to work hard to get it like this, but now I'm here it's so great because I don't have to think about it. I can just enjoy life. What a relief is that," she added.

Emma Watson has admitted that she has become more experimental with makeup after she chopped off her long locks last year.

Watson says that her short haircut has made her become bolder with cosmetic choices as her face is now more exposed.

"I'm more experimental makeup," Contactmusic quoted her as telling a stylist.

"There's no way to hide when you have short hair. You really have to go for it," she added.

Kirsten Dunst says she's all "grown up" and would like to dress her age.

"I'm currently cleaning out my closet of childish dresses," People Magazine quoted the actress as telling T Magazine.

"I want to start dressing like I'm 30. Some of the things I have are like, 'I can't wear this anymore, it's not cute.'"

The star's shopping list included basics from APC and Balenciaga, which she stocked up on after a self-imposed shopping hiatus.

"I didn't shop for a long time," she added.

Francisco Costa, design head of Calvin Klein has revealed that he would love to dress Duchess of Cambridge Kate Middleton.

However, the newlywed Duchess prefers British labels, especially when she is on official duty in Britain, although she has not disregarded international fashion houses.

Soon after their royal wedding, Catherine's fashion stock was on the rise, with everything she wears selling out in seconds.

It is no surprise that the world's top fashion labels are clamouring to dress the Duchess, and the latest is the design head for Calvin Klein.

In a recent interview, Costa said that he would like to work with Kate, as she has all the potential to become a 'style icon', and looked like an 'all-American girl' despite her British breeding.

"She's very Calvin, when you think about it," the Daily Mail quoted Costa as telling the Telegraph.

"She's athletic looking, with great teeth and amazing hair. In many ways she looks like an all-American girl."

"So, yes, I'm putting it out there: I'd love to dress her," he added.

If Catherine were to endorse Calvin Klein, it could amount to huge financial gains for the company, and given how carefully she crafts her wardrobe, it is not entirely unlikely that she could one day choose to wear the brand, should the occasion demand it.

Marilyn Monroe's dress, which the legendary actress wore in the 1954 flick River of No Return has reportedly been sold for 504,000 dollars.

Monroe wore the green velour dress, designed by Travilla while she sang I'm Gonna File My Claim in the 1954 Western, where she played Kay Weston, a gambler's wife.

The dress was sold at an auction in China through Julien's Auctions.

Other items auctioned included Madonna's black bustier with gold accents and black beading, and Princess Diana's black velvet and white taffeta gown, CBS News reported.

Michael Jackson's custom-made black spandex, fingerless forearm gloves with covered thumbs, silver metal buttons and buckle, and a pair of gold metal-framed sunglasses with reflective lenses worn by the late Legend of Pop were also sold at the auction.
