Ricki Lake says Dancing with the Stars could be anyone's game heading into the finals.

"I don't know if I'm in the lead. I think we're all equal -- on an equal playing field -- but I really surprised myself at how well I've done, and I'm so happy to be in the finals with these guys," the former talk show host said alongside fellow contestants Rob Kardashian and J.R. Martinez during a Wednesday morning appearance on Good Morning America

Kardashian agreed with Lake that the competition is too close to call and brushed off former ninth-season Dancing with the Stars winner Donny Osmond's recent prediction that he'll walk away with the thirteenth-season mirrorball trophy.

"Oh wow. That is amazing coming from him... I can't even believe [I'm] in the finals. I can't believe the time has just gone by and I'm super happy to be here, and now we all kind of have a clean slate. We just all have to bring it this week and have a great performance come Monday," the Keeping Up with the Kardashians sibling said. 

While Martinez's ankle poorly affected his performances on Monday night, the Iraqi war veteran and former All My Children soap star explained his injury is not a significant issue and won't impede his chances of dancing to his full potential next week.

"The ankle is fine. I twisted it earlier in the week and then Monday night, during that first dance, I tweaked it a little more. But I've been able to give it some rest and X-rays are negative, so I'll be kind of pacing myself throughout the next week," Martinez added.
