Justin Bieber and Selena Gomez split for second time (Mexico)

JUSTIN Bieber and Selena Gomez have hit the rocks for a second time, according to a US report.

The pair, who reunited in November after a brief split, allegedly had a huge bust-up on holiday in Mexico at the weekend.

Justin and Selena had hoped to get their relationship back on track by jetting away for a seasonal New Year break.

But before they could ring in 2013 it had crumbled once again.

Signs weren't good when teen Justin shared numerous topless pictures of himself with fans on Twitter instead of spending quality time with Selena.  An argument swiftly followed and former Disney starlet and actress Selena, 20, flew home, with the Canadian titan reportedly leaving a day after on New Year's Eve.

On January 1, Selena hinted at a break-up by telling fans: "New beginnings. Fresh start. I love you all "

 A source told the New York Daily News that the couple haven't seen each other since their fight so it's not clear whether they have called it quits for good.

Justin and Selena's relationship has been on thin ice since November, when they split due to their hectic schedules and the pop star's wandering eye.  thesun
