KATHERINE HEIGL starts off the show today! She's got a lot going on right now and always gives an interview you don't want to miss! Then, Ellen's boo, NICK CANNON, is coming by. She loves the guy so much, he was the DJ for her TBS special this summer. Nick is doing well for himself -- he's married to Mariah Carey, is the host of "America's Got Talent," and is the chairman of the Nickelodeon channel, TEENick! Then... when Ellen was 7, she put a nickel up her nose, but 7-year-old PRESTON SCARBOROUGH led police on a high speed chase! Now he's coming here to tell Ellen all about it, but this time we're going to leave the driving to his parents!
