We're not sure if the screams we hear are happiness that he's single, or sadness over his broken heart ... that's right, Justin Bieber and Selena Gomez are over.

E! News was the first to report that Jelena -- as the kids called them -- have gone their separate ways. Well, again. Allegedly.

"Because of their crazy schedules, it was getting harder and harder to maintain a relationship," a source told E!, noting that Selena ended things about a week ago.

People then followed up, with their source adding, "She had some trust issues. It's not easy, but the relationship needed to end."

Justin, 18, and Selena, 20, have been dating for nearly two years. They've reportedly split several times before, and according to TMZ, the Biebs is confident this is just another bump in the road.

"If I was your boyfriend, I'd never let you go..." Well, we'll see about that.
