"She plans to spend next year completely focused on her music," a source close to the 21-year-old singer toldPeople. "She had a great run and a good time."
Lovato's first arena tour begins in early February in Vancouver and will also showcase The X Factor's Fifth Harmony -- who won the show's second season -- Little Mix and Cher Lloyd.
Little Mix won the eighth season of The X Factor's U.K. version, and Lloyd finished fourth in the British series' seventh edition.
Lovato, who also appeared in Glee this past fall, told People last month she planned to concentrate on her music career in the year 2014.
"I think ultimately my main thing is singing," the former Disney Channel star explained.
"Maybe movies once in a while, if the right role comes along. I will take the month of January completely off! 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."
The final performance show of The X Factor's third season will air tonight and be followed by the finale broadcast Thursday night on Fox. Lovato has no artists remaining in the competition, as she mentored the "Girls" category.
