Singer Demi Lovato is reportedly quitting her position as a judge on the US singing reality show "The X Factor".
The 21-year-old, who joined the show's judges panel last season, will not be returning for the fourth season of the show as she wants to focus on her music career.
"She has a great time but she's going to focus on her music next year," usmagazine.com quoted a source as saying.
Lovato released her fourth studio album "Demi" in May, and is now set to embark on her Neon Lights Tour in February. She will be supported by Little Mix and Cher Lloyd.
