In an interview with Star magazine, writer Ian Halperin is claiming that Lady Gaga, 25, is literally starving herself for her career.

Halperin, who has spent a year researching and writing a tell-all book about the pop star, told the mag:

"Those who have worked with her on tour reported to me that Gaga barely ate for weeks at a time to fit into her costume. She is sick and obsessed with her weight. One friend told me Gaga will stare at herself in the mirror for hours on end, analyzing and critiquing her body. It's an unhealthy obsession."

In addition, Halperin, who has also written unauthorized biographies of Michael Jackson and Brad Pitt/Angelina Jolie, says Gaga has tried every drug under the sun.

"From heroin to cocaine and ecstasy, her friends say that she has done every drug conceivable," he says. "You name it, she has done it. ... Her drug use started young."

In Gaga's defense, she has never denied that she used to party hard. Mother Monster admitted that in 2005 she was regularly doing cocaine.

Halperin also revealed that Gaga might be using her costumes to hide a secret about her body ... see what he said after the jump.

Victoria Beckham has been doing an amazing job of hiding her growing baby from the paparazzi, but unfortunately hubby David just blew her cover!

The L.A. Galaxy soccer star posted a Facebook photo of his wife sunbathing Thursday, with the caption:

"Took this pic of Victoria while she wasn't looking. She looks amazing! So close now to the baby being born!"

Ironically, VB had just confessed to Women's Wear Daily she would never expose her baby bump, expressing:

"I'm not really one of those people that likes to go out and pose and flaunt being pregnant. Not like there's anything wrong in that. I'm so proud to be pregnant and I feel so blessed and so happy, I really do. But I'm just not that kind of person."

The Beckham fam is expecting the arrival of their new little girl any day now!

It was a chaotic day on Today this morning as Ann Curry tried to play babysitter and reporter at the same time.

Curry was attempting to interview Nadya "Octomom" Suleman, and her octoplets were making their first live TV debut. Unfortunately 2-1/2-year-olds are apparently not the optimal age for sit-down interviews.

Suleman's children ran all over the set, with Curry having to get up and chase one down at one point! It's adorably ridiculous to watch poor Ann try to ask Nadya serious questions while literally chasing down the kids at the same time!

The mom of 14 was on the show to clear up some rumors -- one being that she's on public assistance. Today said that it costs Suleman $15,000 a month to support her kids, but she says she's never been on public assistance programs, and instead makes her money via celebrity appearances and being a personal trainer. Saisd Suleman:

"I’ve never in my life been on (public assistance), and I never would. I would feel like a failure as a mother and as a human being."

A recent issue of In Touch magazine also claimed that Suleman had said she "hates" her babies -- Suleman came out saying the interview was fabricated.

Megan Fox caused quite a stir when she showed up to the 2009 premiere of Transformers: Revenge of the Fallen with a noticeably swollen face.

Since then, Fox has grown tired of the criticism she's been getting on her "cosmetically altered" face, so the sexy 25-year-old actress took to her Facebook and uploaded some photos with the album caption, “Things you can’t do with your face when you have Botox”.

In the pics, the sexy star furrows her brows and points out naturally occurring lines in her forehead when she raises her eyebrows -- things that cannot be done if you've got Botox ... right?

In an interview with Allure magazine last year, the Passion Play star adamantly denied she's had her lips filled in. Fox confessed:

"My lips are my lips. I would encourage anyone to first speak with a therapist, to try and figure out where this want comes from, because a lot of times it’s not related to your teeth or your nose or your chin - the surgery is not going to alleviate that insecurity for you."

After taking a look at her pics, do you think the Armani spokes model is 100% natural?

Ali Larter is embracing motherhood beautifully, and she always has a big smile on her face when we catch her hangin' out with adorable 6-month-old baby Theo.

The hot mamma is gearing up to reprise her role as Claire Redfield in the next installment of Resident Evil: Retribution, alongside Milla Jovovich.

Larter is spacing out her film projects now that she's a new mom, and the actress recently confessed on getting back to work after baby:

"Never leave your baby. Like most mothers in this country, working moms... you have to go back to work. But it's very, very difficult. The love is greater than anything I've ever felt."

Maybe that $2 million Lorraine Schwartz engagement ring is weighing Kim K down!

The curvaceous reality star narrowly avoided a major fall as she exited a recoding studio in LA, on Thursday. Luckily Kim has lots of practice walking in sky-high heels, and she quickly caught herself before it was too late!

Kim and her little sis Kylie spent several hours in a recording studio -- could they be collaborating on a new album?

We can't imagine how Kardashian has the time! She's been busier than usual trying to plan her wedding to Kris Humphries, which will be televised for the world to see on her reality show.

Could you blame her?
