Lady Gaga said she has undergone surgery to repair an injured hip that forced the pop singer last week to cancel the remainder of her concert tour.
The "Born This Way" singer thanked fans in a blog post on her littlemonsters.com fan website on Thursday, saying the setback was "just a bump in the road."
Lady Gaga is responding to the critics of her 25-pound weight gain with a Body Revolution campaign.
The Born This Way singer, 26, went on her fan site and posted several photos of herself in nothing but her matching yellow bra and panties. One photo caption read: "Bulimia and Anorexia since I was 15."
Lady Gaga is fighting back against PETA, after the animal-rights organization blasted her for seeming to wear fur.
While acknowledging that she respects the animal rights movement, the "Poker Face" singer lays into the more militant factions of the movement, accusing them of waging "violent, abusive and childish campaigns."
