According to People magazine, the singer is leaving "X Factor" to "spend next year completely focused on her music."
"She had a great run and a good time," a source close to Demi told the mag. But, the show's busy schedule is taking too much time away from her passion -- singing.
The 21-year-old has served as a judge for two seasons on the hit Fox show and is set to headline her first arena tour, which kicks off Feb. 9 in Vancouver.
Demi has a busy rest of the year planned, but then she'll have a break before she hits the road.
"I will take the month of January completely off!" she told People last month. "I want to vacation! I want to watch crime shows on my DVR on my couch ... I need to do some exercising and I don't really have time to do it. I love horseback riding and never get to do that stuff, but January is my time to do all of that."
We will be sad to see Demi leave "X Factor!"
