Ellen's All Terrain Game Week is rolling on! Today more audience members compete for a chance to win a brand new GMC Terrain! Ellen has her finger on the censor button today, because her insanely funny WB neighbor JULIA LOUIS-DREYFUS is stopping by. She always keeps Ellen on her toes... it seems like every time she's around, someone gets hit in the face with a rock! Then, before CORY MONTEITH was on "Glee," he had virtually every odd job possible -- including store greeter and school bus driver! Now he's on the hit show and turning into a huge star, and will tell Ellen all about the excitement. Also, Ellen once got the chance to rock out with SLASH, so why can't her friend ADAM LEVINE? The Maroon 5 frontman teamed up with the guitarist on his latest album, "Slash," and today they're both stopping by to perform the song "Gotten." Plus, Ellen has put together some of her favorite moments from the show, and you'll love it!
