Alert all the teen girls in America--Joe Jonas is officially single again.

Sources reveal to PEOPLE that Jonas, 20, and Demi Lovato, 17, have ended their relationship. But they will still move forward with plans to tour together this summer. The couple went public with their relationship just this last March.

Us Magazine is reporting Jonas broke up with Lovato over the phone. This wouldn't be the first time he's done this; he infamously dumped Taylor Swift via phone call in November 2008.
