JENNIFER ANISTON was the very first guest Ellen had on the show -- now she's coming back! Jennifer was in the movie "Love Happens," so naturally Ellen will see if any love is happening in her life! If not, the last time Jen was on she made a few comments about one of Ellen's staff members... maybe Ellen will make that work out! Then, it's their first time on the show and Ellen can't wait, DAVE MATTHEWS BAND is here! They'll be performing "You and Me" from their #1 album "Big Whiskey and the GrooGrux King." Since it's their first time here, Ellen will find a way to make their performance extra-special!
