The Jonas Brothers stopped by The Late Late Show With James Corden tonight to talk about their big reunion. In the interview, Nick reveals that he and his brothers went to therapy for an entire year to resolve the issues that caused them to break up six years ago. The idea of collaborating on music again came up when the brothers were filming their documentary Nick explained:

“About a year-and-a-half ago, we started filming a documentary… tracks kind of our childhood into our time in the band, and it was gonna be a story about where we are today – with separate lives, doing separate things — Joe with DNCE, me with my solo stuff. But during filming and production we started to realize that there was a magic that we felt like we were missing. So the process was basically just us saying, ‘Why don’t we give this another shot?'”
