With Valentine's Day near, Ellen wanted to have some of the sexiest stars on the show -- and there's no one better than Ellen's good friend, DEMI MOORE! Demi and Ashton Kutcher are well known for being a romantic couple; they said they even bought guns together. Ellen and Demi were once in a movie together, but they cut Ellen's scene -- maybe Demi can have it inserted into her new movie, "Happy Tears." Then, in the past year, everyone has noticed the gorgeous CHANNING TATUM in some of the biggest movies. The model-turned-actor is now stealing hearts in the new movie, "Dear John," and might end up stealing your heart too! Also, there's no better musician for this time of year than MICHAEL BUBLÉ. The two-time Grammy-winning artist is here to sing his hit song, "Haven't Met You Yet."
