Holly Madison's hot new body is garnering the attention of more than a few fellow celebrities. The Holly's World star dropped a jeans' size in just two weeks and is feeling more confident than ever in her new, hard body.

It's been nearly thirty years since Carrie Fisher slipped into that intergalatic, golden teenie-weenie bikini in Stars Wars: Return Of The Jedi, much to the delight of humans and aliens everywhere.

Now, Fisher is looking to get back into fighting shape by becoming the latest celebrity spokesperson for Jenny Craig.

Fisher -- who weighed 105 lbs. while making the Star Wars triology and at her heaviest, ballooned up to 180 lbs. -- says she's struggled with her weight for the past three years, and hopes to lose 30-pounds in 2011.  "A day comes when you can no longer face not wanting to leave the house because you don't like the way you look," said Fisher, now 54.

Lady Gaga’s former tour manager David Ciemny claims she was hospitalized six times in 2009. He alleges that the singer goes to dangerous lengths to fit into her eye-catching stage costumes.

“When I say she was sick, I mean physically and mentally,” David said in the new blockbuster book Poker Face: The Rise and Rise of Lady Gaga.

David recalled being on tour with Gaga and said she would binge on sweets and unhealthy food, then not eat for weeks to fit into her costumes – one time losing 20 pounds between fittings.

Further describing bizarre behavior, David’s wife Angela said that Gaga would cuddle up next to her in bed before her performances and beg for her to come back once she left.

“I would say, ‘Gaga, I have a husband to go home to. I’ll be in the room next door,’” Angela said in the book.

“She’d call and text me, ‘I miss you, Ange, can you come back?’ So I would,” Angela continued.

“We literally would do our make-up together every morning and get ready for bed together at night.”

The 24-year-old Bad Romance singer has admitted to being insecure in the past and said, “When I wake up in the morning, I feel just like any other insecure 24-year-old girl.

“Then I say, ‘B**ch, you’re Lady Gaga, you get up and walk the walk today.”

Jessica Simpson often finds her body under intense scrutiny but the bubbly blonde actually wants to get bigger, not smaller. Well, at least in one area of her body.

"I have a white girl booty. I don't have a big butt. I'd rather have a happy medium and take some off my chest and put it towards my butt so I could balance out a bit," Simpson told Closer magazine.

Simpson, who recently started dating former NFL player Eric Johnson, is finally feeling more comfortable in her skin.  "I'm more confident than I've ever been in my life. I'm much more at peace with myself and whatever life brings my way."

Despite the burst of self-assurance, the former pop star still struggles with why her weight always seems to be an issue.

"People talked about my weight for an entire year. Being famous for gaining 10lbs is ridiculous! I didn't feel as fat as everybody was making me out to be,” she added.
