So much chemistry, in fact, that the two might have a side project up their sleeves.
"I did write an amazing song with Nick Jonas and we want to do something with that, but we are not quite sure, so maybe we can do a side project together," Demi told MTV News this week. "We may or may not have picked out the band name already."
While she wouldn't give up the band name, she did continue when asked if we could expect a duet album, "I know he's working on his new album too, so it might not be for awhile, but the two of us... I'm always writing songs and he's always writing songs."
Nick served as creative director to Demi's Neon Lights Tour, and while she's in the early stages of planning her Demi: The World Tour, she knows her former "Camp Rock" co-star will somehow be involved.
"I actually haven't started the process, so possibly," Demi said of working with Nick on tour. " I know he's busy doing a TV show now, but he's gonna be involved somehow whether that's performances or not. Inevitably we end up on the same team, musically. It just always happens."
Demi Lovato's "Really Dont' Care" video premieres Thursday, June 26 on MTV, MTV Hits, and LOGO at 5 p.m. ET. And don't miss her on Logo TV's "Trailblazers" special, also on Thursday, June 26 at 9/8c.
