Skinny to Solid: Supermodel Devon Aoki Forced to Beef Up by Training With a 30-Pound Gun

Devon Aoki is one of the most familiar faces and figures in the high-fashion world today, but even though the Japanese/German/British beauty was considered Karl Lagerfeld’s muse and has graced the covers of Japanese and Russian Vogue, she still struggles with insecurities and image issues.

"Everyone has their own insecurities, regardless of how you look or how people perceive you, but sometimes people give their insecurities too much power." Aoki told Tarts in an exclusive interview. "Defining beauty is simply a matter of opinion. For me, real beauty has very little to do with the structure of someone's face or body."

Given the constraints of the couture world it comes as no surprise that the 26-year-old stunner recently decided to strut off the runway and focus on an acting career and as her latest role in "Mutant Chronicles" attests, it’s a far cry from the glamour of Givenchy or the posing in Prada.

"I had to pump my arms up quite a bit. They were a little on the weak side when we started and by the end of filming, I was pretty rock solid," Aoki said. "The funny thing was most the boys got dummy guns that weigh very little, and I got the real McCoy! I was running around with a 30-pound gun under my arm for the entire film. That might have been their way of telling me I needed some muscles!"

But before hitting the big-time as a ONE model and being featured in campaigns for Lancôme, Chanel, and Versace Aoki had to snag clothes (and some fashion sense) from Kate Moss’s wardrobe.

"At the start of my career Kate was very helpful and pushed me for some jobs, she is very sweet," Aoki told Tarts in our exclusive interview. "I was attending an event in Paris one year and had absolutely nothing to wear, except for a pair of Doc Martens or some ragged jeans and without a moment of hesitation she picked out one of her own beautiful dresses for me. It was very generous and I never forgot it."

Lindsay Lohan the Victim of Twitter Hackers?

Earlier this week Lindsay Lohan was so "bored" that she posted a topless photo of herself on Twitter, prompting many to speculate that the not-so-reformed rehabber was losing her mind. However Linds took to her Twitter page to blame the posted pic on her sister’s doing.

"Haha-the photo of me for FORNARINA in THE TRAILER was sent by my sister as a PRANK," she wrote. (Mind you, LiLo didn’t bother to remove it).

But if that wasn’t controversial enough, the 22-year-old is now claiming somebody hacked into her Twitter account and tweeted that Justin Timberlake was cheating on longtime girlfriend Jessica Biel at NYC club Avenue, even posting a pic from inside the hotspot.

"Stop trying to get onto my twitter page whoever you are! Its become extremely creepy!!! I don't twitter about my personal life! Let alone, someone else's life! I've learned my lesson some time ago," Lohan wrote on Thursday morning. "Just trying to clear the air! And I'm tired of changing my password every other day!"

So it Linds telling the truth or just trying to cover her tracks?

According to an inside source, the actress is still desperately trying to work things out with ex Samantha Ronson and when she gets like this "she says things without thinking". The club’s rep has since spoken out and made it clear that celebs that twitter about other celebs are "not welcome"…

A rep for Lohan did not respond for comment.

Holly Madison: Criss Angel Dates a Different Person Every Week!

After calling it quits with Hugh Hefner, Holly Madison quickly fell in love again, this time with Vegas magician Criss Angel. While the two lasted an intense four months, the busty blonde initially just assumed she would be his flavor of the week.

"He dates a different person every week so I didn’t think anything of relationship status would happen," Madison told Las Vegas Weekly. "But we would text each other and when I would come out here to work on a photo shoot and it was the first time I’d come out here by myself, we decided to go out together, and I thought that best-case scenario we would be friends with each other, but we just totally hit it off and we got together."

In February the dynamic duo made the surprise announcement that they were calling it quits - although it sounds as though that was a result of something a little deeper then things simply just not working out.

"I think it happened because some people don’t want to be happy and they always look for problems, even if there aren’t any," Madison added. "Some people don’t want to be happy, so they pick away at something until they find problems. I would have done anything to make it work. He’s the one with the problem, not me."

Needless to say, the former flames no longer have any contact at all.

"Hollywood Types" Get Upset at Ryan Seacrest’s Restaurant Opening

It looks as though the Global Economic Crisis is causing Hollywood’s slew of professional party people to go to desperate lengths for a free night on the town. Sunset Boulevard was a mess on Wednesday evening as hundreds of Hollywood agents, reps, actors and wannabes congregated outside the Grand Opening of the Ryan Seacrest-invested restaurant, BOA Steakhouse.

But there was more entertainment going on outside than inside the chic new dining hotspot as L.A’s "scene" stars and socials aren’t really used to being told to wait in a line (as per orders from the fire marshals). There was pushing, shoving and tears as people threw around "Don’t You Know Who I Am?," demanded they "speak to a manager", pretended they worked for Variety Magazine and one very distraught young female (whose dress left very little to be desired) even insisted that she recently had a guest spot in a popular reality show so she "deserved to be let inside immediately."

But for those who stuck around, it was worth the wait - every area of the large new restaurant was decked out with a special feature from chocolate fountains to wine bars to cotton candy to Kobe beef.

However the one celeb getting more attention than Mr. Seacrest himself was Los Angeles Laker, Sasha Vujacic. The NBA star was literally mobbed as he was escorted inside and everywhere he went starstruck party peeps chanted "world champ!" Vujacic eventually got some downtime when he hung out in the back with Seacrest and the two chatted over mini beef burgers. Other attendees included Shanna Moakler, Eva La Rue, Joe Francis, Kim Porter and Garcelle Beauvais-Nilon.
