Well, for those hoping Selena Gomez and Justin Bieber would be in it for the long haul, sorry to crush your dreams.

The on-again, off-again twosome were spotted in Mexico in late Dec. 2012, as they planned on ringing in the New Year together. However, before the clock struck midnight, Gomez and Bieber allegedly had such a massive fight, they decided to break up for good!

Believe it or not, sources are saying the duo never even made it to New Year's Eve, as Gomez was seen flying out of the country on Dec. 30, with Bieber following suit a day later. The two have yet to see each other following their argument.

“They keep breaking up and getting back together,” said an insider to The Daily News. “It's an on-again, off-again relationship. It's probably not correct to characterize this as a final breakup."

Another insider told the paper that the split has taken quite the toll on the Biebs and his career. "She’s been giving him a really hard time,” the insider told the Daily News’ Confidenti@l column. “She’s been partying without him, and it drives him crazy.”

Could this be the official end for one of the hottest young couples in the biz?!
