GREG KINNEAR is never afraid to tackle a new project -- his latest is causing quite a controversy! He's starring in the miniseries "The Kennedys," which one network refused to air! He'll clear up the story when he stops by today. NIGEL LYTHGOE is ... (more)back as Executive Producer of "American Idol" -- and he's made some changes! Today he's stopping by to share them with Ellen, and to let everyone know what to expect for the rest of the season! At just 13, SAOIRSE RONAN was nominated for an Academy Award! The Best Supporting Actress nominee is here today to meet Ellen -- and will tell her all about the exciting night, as well as her movie, "Hanna." It's always a party when the legendary rock band HEART is here -- they helped kick off Ellen's 50th Birthday Show! Now they're back with a live DVD of their classic hits and will perform one today!
