Two incredible legends are here for one very special day on Ellen!

First, one of the most beloved women in Hollywood -- DIANE KEATON is here! From "Annie Hall" to "Something's Gotta Give" to all three of the "Godfather" films, there is no one that's quite like her. She's telling Ellen about her new film, "The Big Wedding," in which she's starring with Robert De Niro, Robin Williams and Susan Sarandon!

Then, a music legend like no one before him -- it's JON BON JOVI! The incredibly handsome and ever-charming rock star is here with his awesome band to perform their new song, "Because We Can," from their upcoming CD "What About Now," and one of their classic hits!

This Monday, Ellen is sure to be a classic!
