It's the Summer Preview Show! And Ellen is getting ready for summer with some amazing guests! The fantastic TOM HANKS will be here to tell us about his big summer film, "Larry Crowne," which, aside from starring in, he also wrote and directed! 50 CENT will make his first "Ellen" appearance with NICOLE SHERZINGER to perform their new duet "Right There" -- from Nicole's upcoming solo album. Also, one lucky audience member will win the trip of a lifetime... to the premiere of one of the biggest movies of the summer, "Harry Potter and The Deathly Hallows: Part 2"!
