While performing in American Music Award Jennifer Lopez injured butt in fall

The singer-and-actress fell during her performance at last month’s American Music Awards and injured her famous derriere in the process.She said: "I have a bruised bone. What happened was one of the dancers' backs was slippery from sweat and lights and everything. We never bargained for that because they always had T-shirts on in rehearsal."So they were bare-backed, didn't have shirts on for the performance, and when I stepped on their backs my feet got wet. So when I landed, it just slipped from under me."Jennifer was performing her new song ‘Louboutins’ and credits adrenaline with helping back onto her feet so quickly.She added to US talk show host Ellen DeGeneres: "That's kind of what I felt the rest of the performance, ‘Did I fall?’ It happened so fast. I was up and all I could think was, 'I have to get to the next beat. I have to do this dance solo right now.’ I had no time to think about it.""Then I get to the back, and one of the dancers was like, 'Are you OK?' 'Oh my God that's right, I fell.’ It was awful, but you know, it happened."
