For over a decade, CHRISTINA AGUILERA has been one of the top pop music superstars -- and now she's ready to help the next big star make it to the top! Christina is a coach on the brand new show, "The Voice," and will tell Ellen what to expect when it premieres tonight!

She's always looking for the newest and most outrageous show to share, and she'll tell Ellen what she's found today -- along with what to expect on the brand new season of her show, "In Plain Sight." Since winning season 7 of "American Idol," DAVID COOK has been going non-stop!
