This week we've got tennis legend Martina Navratilova and TV host Maria Menounos. In the first video, Navratilova talks about her biggest competition. She feels that even though fellow competitor Gladys Knight says she hasn't danced, she still has the musicality to be a contender. Menounos says she's competing against herself. Ladies, don't count Jack Wagner out. Have you seen what he can do with his leg?

We can't wait to see who can overcome nerves, sore muscles and the roar of the crowd to wow us with their dancing skills. Will you be watching the premiere? Zap2it will be live on the scene, chatting with the dancers. Stay tuned!
