Oscar-winner DIANE KEATON tried it all in her new movie, "Morning Glory" -- including dancing with 50 Cent, going up against a sumo wrestler, and even kissing a frog! Today, Ellen will see what else she'll do! You know JULIANNE HOUGH from, "Dancin... (more)g with the Stars," now she's becoming a star herself in the new movie "Burlesque," and she's stopping by to tell Ellen all about it. NELLY is back with a brand new album, "5.0," which is out today! He's here to perform his hit song, "Just a Dream."
