She’s a former Disney star with plenty of experience as a tween sensation… And, now Demi Lovato will be sharing her knowledge to help other potential artists realize their tweenage dreams…

In her new role as a judge on Fox’s The X Factor, the 20-year-old part-Mexican American singer/actress will serve as a mentor to solo singers between the ages of 12 and 16.

And Lovato, who ranked as one of Billboard.com’s 21 Under 21 last year, will be getting an assist from her former Camp Rock co-star, Nick Jonas. He’ll mentor Lovato’s team during the judges’ house round, according to The Hollywood Reporter.

During this phase, the judges will mentor 32 acts who are divided into four different categories (8 acts in each category).

Along with Lovato handling the solo singers ages 12 to 16, Britney Spears will mentor singers ages 17 to 24, L.A. Reid will guide contestants ages 25 and over, and Simon Cowell taking on the groups.

The second season of The X Factor will premiere Wednesday, September 12 at 8:00 pm on Fox.
