"I started the show being a singer and a musician, and so I'm going to go back to that," Lovato told the Hollywood Reporter Wednesday. "It's been really great, but I'm so excited for 2014. I'm going to dedicate it completely and entirely to music -- touring and making a new album. Possibly releasing one."
Simon Cowell, the singing competition show's creator and producer, also confirmed Lovato's departure Wednesday.
"I always knew she wasn't coming back because she's touring, so I knew that," Cowell, who is also a judge on the show, told THR.
This season of "X Factor" is to wrap up Thursday.
