Mark Ballas was not quite ready to say goodbye to the ballroom - and is ready to vie for the mirrorball trophy with Whitney Leavitt on Dancing With the Stars season 34. "I had some injury stuff clear up that was kind of slowing me down," Mark, 39, exclusively told Us Weekly on Wednesday, September 3, about his return to the show, noting that his body is "feeling good" after some "hardcore" physical therapy. Mark took a hiatus from Dancing With the Stars after season 25, returning for season 31 in 2022 - which he won with TikTok's Charli D'Amelio.
