Jennifer Lopez is nursing a bruise on her famous backside after slipping onstage during her performance at the American Music Awards on Sunday (22Nov09).
After strutting onto a stage converted into a boxing ring in a robe and gloves, to sing Louboutins from her new album Love?, Lopez gyrated with male dancers.
But it all went wrong for the star after she climbed onto a human pyramid of half-naked performers and jumped down - slipping backwards onto her bottom and flashing a glimpse of her underwear.
Ever the true pro, Lopez swiftly leaped to her feet and carried on her performance.
