Did you think it would last forever??

Over the weekend, Justin Bieber and Selena Gomez called it quits! A source says that their 'crazy schedules' are to blame. Whether or not that's true, beliebers all over the world are rejoicing.

Oh, and last night, he performed Justin Timberlake's "Cry Me A River" at a concert in Boston...hmmm! What really happened??
