They say things always happen in threes, and after first J.Lo, then Adam Lambert falling down on stage at the AMAs, Kelly Osbourne completed the trinity by stumbling in her freestyle disco routine for the finale of Dancing With the Stars.

Luckily, Kelly, who got stuck between partner Louis Van Amstel's legs, didn't let the misstep put a damper on her evening. In fact, the mess up made her get the uncontrollable giggles in the middle of her routine!

Despite the mistake, which may cost her the mirror-ball trophy, "I had the best time," said Kel.

Kelly's judges' score of 76 puts her in third place behind Mya, who leads with 87 and Donny Osmond, who's a close second with 85.

But of course, everything could change when they tally the viewers' votes. Who do you think will win tonight?
