Canadian star Justin Bieber has reportedly split from his Disney singer girlfriend Selena Gomez after a huge row on New Year's Eve.

Tabloid reports state that the teen duo were holidaying in Mexico over new year after a brief split in late 2012. The youngsters had reconciled their differences, but have now apparently split for a second time.

Gomez hinted at the split with a New Year's tweet, in which she said to followers: "New beginnings. Fresh start. I Love you all :)"

New York Daily News reports that the pair split after their fight and have not seen each other since. The pair's relationship was said to be struggling due to each of their work commitments - which, in recent months for Bieber, has included performing a show with nearly-naked Victoria's Secret models at a US underwear show.

Bieber has faced a tough 2013 so far, after a man was killed while he attempted to take a photo of the Canadian singer's car - which he was not driving at the time.

Bieber had been partying with Lil Twist at the Four Seasons in Beverley Hills when Lil Twist borrowed Bieber's car to go for a drive.

The photographer was following the car as he expected Bieber to be driving it, and was hit by a car after walking across the Sepulveda Boulevard to take a photo, as the car had been pulled over for a routine check.

Lil Twist did not witness the accident.

The photographer has now been identified as Chris Guerra, who is 29. He was reportedly obsessed with photographing Bieber, and worked exclusively on covering Bieber's movements.
