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."
