Derek Hough is questioning claims that Ryan Seacrest had to lecture him about his behavior on the Celebrity Wheel of Fortune set. Seacrest, 50, recalled having to jump in during Hough's appearance on a September episode with fellow contestants and Dancing With the Stars cast members Jenna Johnson and Bruno Tonioli. Hough, 40, apparently hopped on the game show's 2,400-pound wheel, at first mounting the podium, which isn't permitted.
