Also on the show, Sweet Home Alabama star Kelsey Smith drops by to talk dating. Plus, see Sheryl Crow's exclusive performance of her new single, "Callin' Me When I'm Lonely." Then we'll tell you what Jake Owen is thankful for this holiday season, and you have to see Neil Perry of The Band Perry's impression of Luke Bryan.
