Joe Jonas Can't Wait to Tour with Demi Lovato

What's a break-up between close friends?

While Joe Jonas and Demi Lovato ended their romantic relationship in May, the pair still talk glowingly about each other in public and will soon go on tour with one another. Might this cause tension?

No way, Joe told Ryan Seacrest on his radio show today. He said: "Demi [Lovato] has been a friend of mine for a long time. I think that our friendship is so strong that it surpasses a lot of things and I think touring will be a lot of fun."

Starting on August 7, Lovato will open for Joe and his brothers as they all travel the country together.

Jonas says everything has "definitely been cool" between him and Demi since they split, making the duo about 16 billion times more mature than Michael Lohan and Kate Major.

Joe, meanwhile, recently returned from a charitable trip to Africa. He's pretty much perfect.
