Introducing him as one of her “greatest friends”, the new X Factor judge invited Nick Jonas out on stage for a few songs.
In 2010, Lovato was on tour with the Jonas Brothers when she abruptly left to check into rehab for drug, self-injury, and other psychological issues.
Still, she and Nick have remained friends, even after she breaking up with his brother Joe just before she entered rehab.
Wednesay, the two friends sang “Catch Me” and “Don’t Forget”.
It looks like these former Disney kids are growing up.
