The "dawg" is coming to Ellen! RANDY JACKSON misses Ellen so much, he couldn't miss a chance to visit! He'll stop by and share all the behind-the-scenes details on this season of "American Idol"! Lots of people know just how wonderful dancing can ... (more)be -- especially CHERYL BURKE. Not only is she a two-time champion on "Dancing with the Stars," she credits dancing with changing her life. She'll tell Ellen all about it when she stops by to talk about her new book. A college student named NICHOLAS CORRALES became an unwitting YouTube star when he went to dunk a basketball during an acrobatic halftime performance -- and ended up dunking himself! He's diving right in to the show today to visit Ellen!
