Lady Gaga, criticized in the press recently for gaining weight, launched a new "Body Revolution" project on her LittleMonsters website, hoping to help build confidence in her fans who might have body-image issues.

The pop star revealed she has suffered from bulimia and anorexia since she was 15 and released a photo of herself dressed in underwear with no make-up to show solidarity with her fans who have posted their own images.

"My weight/loss/gain since I was child has tormented me. No amount of help has ever healed my pain about it," she wrote. "But YOU have."

"I have been startled and overwhelmed with pride and emotion the past few days … seeing you post photos of things on your bodies and in your minds that you feel society tells you you should be ashamed of," she continued.

"You are showing them you have no shame. You are brave, strong and accepting not only of yourself, but of others.. You are proud to be born this way, and brave in your vulnerability with this community. Watching you all create a safe space online for people to be compassionate is the greatest gift you could ever give me."
