Getting ready to kick off their Future Now tour later this month, Demi Lovato and Nick Jonas stopped by The Late Show on Thursday (June 16) and got candid about Barney and always being in the shower. But while their interview with Stephen Colbert was adorable, there was one major cringeworthy moment.

After learning both singers started in the entertainment business at a young age, Colbert noted how neither has had any child-star meltdowns. Raising her hand, Lovato admitted, "Well, I went to rehab, so ..."

Then, to try and assuage any awkwardness, Colbert and Lovato joked with Jonas about when he was going to "catch up" with her and go to rehab, too. "Hopefully not anytime soon," the JoBro said, laughing nervously.

The trio later discussed Jonas, Camp Rock, and how Joe Jonas "burned" Lovato when she was younger and ended up putting Nick in the big middle.
