Lady Gaga Strips Down to Underwear, Reveals Bulimia and Anorexia Battle (PHOTOS)

By: Lily Harrison / September 25, 2012

Lady Gaga — or as her fans call her, Mother Monster — is baring all.

The pop star took to her Twitter and posted photos of herself in her underwear on her website, LittleMonsters, in an effort to start a what she’s calling a “body revolution.”

Gaga revealed that she has suffered from bulimia and anorexia since she was just 15-years-old.

What did the singer reveal about her recent weight gain?

Gaga admitted on Sirius Radio’s Elvis Duran show on Sept. 20 that she’s packed on a whopping 25 pounds over the past few months.

“I really don’t feel bad about it, not even for a second,” she told Duran. “I have to be on such a strict diet constantly. It’s hard because it’s a quite vigorous show, so I tend to bulk up, get muscular, and I really don’t like that.”

She added, “I’m a New York Italian girl. That’s why I have been staying out of New York. My father [Joe Germanotta] opened a restaurant. It’s so amazing … it’s so freaking delicious, but I’m telling you I gain five pounds every time I go in there. So my dad wants me to eat at the restaurant, and I’m, like, I’ve got to go where I can drink green juice.”

Now — amidst reports of her record company demanding she slim down — the 26-year-old is trying to trim her waistline. “I’m trying to find a new balance,” she said.
