Derek Hough made a reference to Ryan Seacrest and Julianne Hough's past relationship during a recent appearance on Celebrity Wheel of Fortune. Derek, 40, was a contestant on the game show hosted by Seacrest, 50, alongside fellow Dancing With the Stars costars Bruno Tonioli and Jenna Johnson. At one point during the game, Derek solved the puzzle phrase "Footloose and Fancy-Free," sparking a conversation about the musical Footloose. "You were in Footloose back in the day, weren't you?" Seacrest asked the DWTS judge.
