Bad news, Jelena fans. It looks like Justin Bieber and Selena Gomez have split once again. And could it be for good?

The drama reportedly started with a huge argument for the couple over the New Years holiday in Mexico. According to the Sun, the twosome fought like cats and dogs during what should have been a romantic trip.

One of the problems, apparently, was Justin tweeting numerous topless photos of himself with fans, rather than spending any time with Selena.

The fight was so intense, the newspaper said, that Selena jetted out of Mexico and back to the U.S. the very next day. Justin, not wasting any time, then headed to Los Angeles.

The holiday was planned for the couple to spend New Years together, but those plans were cancelled after the blowout.

“It’s just high school stuff,” a source told the paper about the nature of their conflict.

Selena, however, seems to have been putting the incident, and possibly the relationship behind her. She recently tweeted (https://twitter.com/selenagomez) “New beginnings, fresh start. I love you all” on New Year’s Day. She has also been posting pics with friends and family.

Justin, meanwhile, tweeted a less cheerful message to his followers. “2013 got some big things coming…. gonna stay positive.”

“Selena’s been giving him a really hard time,” the source for The Sun says. “She’s been partying without him, and it drives him crazy.”

The couple’s relationship had been shaky for a while now, following a brief breakup in November where Justin was allegedly seen on a date with Victoria’s Secret model Barbara Palvin. Selena and Justin seemed to patch things up back then, but this time it looks like the split could be for good. The twosome have not seen each other since the New Year’s incident.

“They keep breaking up and getting back together,” says the source. “It’s an on-again, off-again relationship.”
