Demi Lovato has already shown how amazingly multitalented she is -- but did you know she also does impressions?!

The singer-actress-author busted out an impromptu impression of the legendary Cher on Wednesday (Oct. 1), during an Instagram Q&A with her Demi World Tour tourmate Christina Perri.

As one would expect, Lovato chose to sing Cher's iconic 1998 hit 'Believe,' but one probably wouldn't expect it to be so hilariously spot-on, arm movements and all. Christina cracks up as she sits on the couch alongside Demi. Being on tour alongside these two certainly looks like it would be a blast!

Further proof of that? Demi's recent interview in which she openly discussed her many onstage falls and the fact that it's an ongoing joke with her fans.

Demi's tour with Christina lasts through the end of October. Check out the rest of their online chat at Demi's Instagram!
