Sneaky bro Joe Jonas caught Nick in the act...of singing "Let It Go" along with Demi Lovato! See, celebs are just like the rest of us.
Nick and Demi both performed recently at the Time Warner Cable and Lifebeat's MTV VMAs concert in LA – and he was spotted checking out pal Demi's set like a true Lovatic.
Joe captured the video on Snapchat, where Nick is seen singing along to Demi's vesion of "Let It Go" from the Frozen soundtrack. And not just casually humming along either – he goes full-out, with dramatic hand gestures and oh-so-much-emotion.
All this Disney-related lovin' really has us wishing the old gang would have joined forces at the VMAs for an epic "Send It On" reunion.
