Joe Jonas & Demi Lovato Split

Joe Jonas has pulled the plug on his relationship with fellow Disney teen sensation Demi Lovato, JustJared.com has confirmed.

However, Joe, 20, and Demi, 17, will still tour together this summer for their Jonas Brothers/Camp Rock 2 concert.

JustJaredJr.com interviewed both of them last week — in separate rooms — but neither looked edgy. Demi smiled throughout, played charades with us and even pretended to bark like a dog. Woof!

Video coming soon to JJJ!

FYI: Back in October 2008, Joe dumped Taylor Swift over a 27-second phone call.
