Kelly Osbourne Injures Ankle On Stage (VIDEO)

With her rock 'n' roll pedigree, you'd think Kelly Osbourne would be a natural on stage, but apparently even Ozzy's daughter can be a little clumsy in the spotlight. Kelly was visiting her mom, Sharon, at "America's Got Talent," when she fell in front of the studio audience. She tweeted about the incident saying "I tripped on the stage like a dumb ass while visiting my Mumma at #AGT I have the worst luck it had to be In front of the whole audience!!!" Later, she added a picture of her injury, with the caption "I have a golf ball on my ankle!"
