Kelly Osbourne on 'Dancing With the Stars'

Kelly Osbourne took a minor tumble during her “I Will Survive” freestyle disco routine, landing between partner Louis van Amstel’s legs. But hey, at least she kept grinning like she was having a blast even after the spill!

Osbourne knows winning Dancing With the Stars may not be in the cards for her. “I definitely came into this competition raw,” she told Us magazine, “and I don’t think I’m gonna win.” Considering Mya and partner Dmitry Chaplin pulled a near-perfect score and Donny Osmond and Kym Johnson were close behind, we’re thinking Osbourne is probably right.

Amstel and Osbourne blamed the fall partially on slick body oil applied to the competitors before the group dance. “It was so slippery!” Amstel said, “I knew she was going to get taken down when we did the helicopter.”

Yeah, lubing yourself up with sparkly body oil before swinging around your partner like a money is probably not a good thing. Even if Osbourne and Amstel don’t take the big prize though, we applaud them both for a great season on DWTS!

The Dancing With the Stars 2009 cast is perhaps the strangest mix of contestants yet. The announcement of the DWTS season 9 cast was made on Good Morning America on Monday by host Tom Bergeron. Bergeron also discussed a few changes to the DWTS format for season 9.

“In the middle of our season, over three weeks, we’re going to have double eliminations,” Bergeron said. “We’ll lose about half of our cast within that period. It will be a ballroom bloodbath.”

We can’t wait. Check out the full cast list below:

• Aaron Carter
