Justin Bieber and Selena Gomez Break it Off Again, Is this the Final One?

Teenage couple Justin Bieber and Selena Gomez have reportedly broken up yet again and this time it's because Gomez is giving Bieber a "tough time."

According to a report by NY Daily News, Bieber's winter holiday getaway with Gomez to Mexico didn't quite turn out the way both of them would have liked. Reportedly the two had a fight and broke off yet again. Ever since the duo haven't been seen together.

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

According to the report, after the heated argument, Gomez took the flight home Dec. 30 and Bieber returned back a day later.

A source tells the tabloid that the reason for the break-up this time round because Gomez had been "partying" without the Biebs, and "it drives him crazy."

"She's been giving him a really hard time," an insider told the Daily News' Confidenti@l column. "She's been partying without him, and it drives him crazy."

In November, both E! Online and People confirmed news of the two breaking up but both tabloids gave different reasons for the breakup. According to E! News, the two couldn't cope with their "crazy schedules" and things in their relationship were getting difficult to handle.

"Because of their crazy schedules, it was getting harder and harder to maintain a relationship," the source told E! News.

According to People magazine, Gomez broke up with Bieber because she was having some trust issues. The magazine also confirmed it's been a week since Gomez broke up with Bieber.

"She broke up with him about a week ago," a source tells People. "With them being apart so much it got complicated. She had some trust issues. It's not easy, but the relationship needed to end."

The two did manage to mend fences within a week.
