When the adorable 8-year-old JOHN TEAS sang for the very first time at his school's talent show, he had no idea it was going to make him a star! Ellen saw the video and she had to get him here -- you don't want to miss his performance! We'll also see just how skilled some of Ellen's audience members are when they compete in Ellen's wild new game. Hopefully, they'll do better than her writers! The last time MARISA TOMEI was here, she taught Ellen how to stay in shape -- by hula-hooping! The Oscar-winning actress was onto something; now she's got a brand new fitness DVD and has some more great tips for Ellen -- and you! Also, the amazing TONI BRAXTON is here to perform her song, "Hands Tied," from her CD.
