Even Demi, when asked in recent interviews, hasn't revealed whether or not she will be back on the talent competition, though Lovatics have been crossing their fingers that she will return for another season.
A source tells HollywoodLife.com that Demi's return is "mostly a lock"--though, of course, there has been no confirmation from the singer or the show.
Demi is also reportedly planning to work with last season's girl group, Fifth Harmony, as the source tells HollywoodLife, Demi will "most likely" collaborate with the group on one of their singles.
She would also perform the song live on X Factor with Fifth Harmony, according to the source.
