One of the hottest stars around is here today -- ROBERT PATTINSON! When the sexy guy stopped by last year, he had just cut off his curly locks for his new movie, "Water for Elephants." There's no telling what hairstyle he'll have today, but he's guaranteed to look great! Ellen isn't the only one watching the Royal Wedding! "So You Think You Can Dance" host CAT DEELEY found five wedding fanatics, and she's taking them on the trip of a lifetime to London for all the festivities! She'll share the details when she drops by, and will hopefully have an extra invitation for Ellen!
