Hough starred as a pro on DWTS from 2007 to 2009, and won two Mirror ball trophies, before becoming a judge on season 19 in 2014. She continued to judge every season except for season 22 last year.
Though the blonde beauty recently tied the knot with Brooks Laich, ET's source says her new marriage (and Laich's hockey career) wasn't the reason for her leaving the show. "It has nothing to do with her husband's schedule. She is so not that person," the source reveals. "She would never ever sacrifice her career for her husband."
ET's source did note, however, that those close to Hough were "surprised" by her decision to leave "something so stable," but that it's possible she will return to the show in the future.
"DWTS is a consistent gig with a steady paycheck. Often these dancers try to move on to what they hope are greener pastures only to realize that’s not the case," the source explains. "For Julianne, she is still on very good terms with everyone over at DWTS and no bridges were burned. Perhaps she’ll be back in the future.”
Longtime judges Len Goodman, Bruno Tonioli and Carrie Ann Inaba will all be back for season 25.
