OTRC: Lady Gaga's 'Body Revolution': Singer shares half-naked photos, reveals bulimia, anorexia

Lady Gaga is hoping to encourage body acceptance with her new initiative, "The Body Revolution," following postings of unflattering photos of her in concert and a radio interview in which she said she has gained 25 pounds.

"Body Revolution 2013," she Tweeted on September 25 to her 29.7 million followers, with a link to a photo of her posing in only a bra and underwear (Photo above). The caption to the photograph reads, "Bulimia and anorexia since I was 15."

The singer, who calls herself, "Mother Monster" posted two more photos. In one, she posed with her arms above her head. The other shows her displaying her backside (NSFW). The captions read: "To inspire Bravery. And BREED some [expletive] COMPASSION. But today I join the BODY REVOLUTION."

The performer who is the self-proclaimed "Devil of Pop," posted the photo, revealing that she has struggled with eating disorders since she was 15 years old. The move prompted many of Gaga's fans, aka her "little monsters," to follow suit. On the website, scores have uploaded pictures of themselves that highlight their own insecurities about their bodies - such as their own eating disorders as well as scars from cancer treatments, self-harm, or skin diseases. One Gaga fan, Amanda, commented on Gaga's photo and explained how the initiative has already inspired her.

"Seeing you embrace you body especially under such a harsh microscope has giving me so much power over my negative self talk," the Little Monster user posted. "I thought..'Wow, Gaga deals with the same struggles that I do.' You have no idea how inspiring it is too see you and here you say you still love yourself and you're beautiful no matter what. You always will be to me and so many others. Thank you for speaking out and helping me learn how to love myself and accept myself."

Gaga, 26, is known for her rallying and philanthropic efforts, such as her Born This Way Foundation which aims to combat bullying and "to foster a more accepting society, where differences are embraced and individuality is celebrated."

The performer said on her website that the new "Body Revolution" initiative stemmed from the foundation, and encourages her fans to "be brave and celebrate with us your 'perceived flaws.'"

Gaga had last week addressed her recent weight gain during an interview on a morning syndicated talk show.

"I'm dieting right now, because I gained, like, 25 pounds," Gaga told radio host Elvis Duran, according to Us Weekly magazine. "And you know I really don't feel bad about it, not even for a second. 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. So I'm trying to find a new balance."

In April, the singer made headlines when she posted a Tweet that had many people furious.

"Just killed back to back spin classes. Eating a salad dreaming of a cheeseburger #PopSingersDontEat #IWasBornThisWay," she Tweeted.
