One of Ellen's all-time favorite shows is "Dexter" -- and today Dexter himself, MICHAEL C. HALL, is finally here for the very first time and Ellen's getting the scoop on the exciting new season.

Last year, TONY DANZA took on one of the hardest jobs in America -- he became a high school English teacher! His new show, "Teach: Tony Danza" follows his experience, and he'll tell Ellen what it was like.

Ellen saw a video of C.J. HOLLAND & DAKOTA BRADLEY singing, and had to get them here! They'll be performing a beautiful song for her today.
