Despite getting stuck in an elevator earlier this week, nothing could stop the Jonas Brothers from performing this morning on Good Morning America. Joined by fellow Disney star (and Joe Jonas' girlfriend) Demi Lovato, the JoBros kicked off the GMA Summer Concert Series in high spirits.

Kevin Jonas declared on stage this morning, "It's going to be a summer like no other.” He’s definitely right about that one! The Jonas Brothers, along with Demi and cast mates from Camp Rock 2 will be going on a summer tour to help promote the TV movie, set to hit Disney later this year.

Jonas Brothers fans can expect old favorites to be played on tour, along with “new music from the film, new music from our television show this summer and new Demi music," Kevin told GMA last week.

It’s also the first tour as a couple for Demi and Joe, who don’t know quite how they’ll handle it yet, as Joe commented, "this should be fun." Kevin is also bringing his new wife, Danielle on tour along with their dog, Riley. Talking about his marriage, Kevin said, "It's great. It's amazing being with your best friend every day."
