It's been seven long years since the hilarious DAVID SCHWIMMER has been here, but today he's finally back! Everyone knows him from his popular role as Ross on "Friends," but he's just as talented behind the camera too -- he's directing a brand new movie! When MICHAEL GRIMM won "America's Got Talent" last year, not only did he visit Ellen and give an unbelievable performance, he proposed to his girlfriend on the show! Now he's ready to release his debut CD -- and it's all going to help his grandparents rebuild after Katrina!
