JUSTIN Bieber, the Canadian singer, has reportedly split up with his girlfriend Selena Gomez.
The pair blamed their hectic schedules for the split, with Bieber touring to promote his latest album, while 20-year-old Gomez is filming a ' Wizards of Waverly Place' reunion.
"Because of their crazy schedules, it was getting harder and harder to maintain a relationship," a source told American TV channel E News.
The pair were a permanent presence in American teen magazines, and were described as a 'teen power couple'.
Gomez is a designer, singer, actress and UNICEF ambassador, while Bieber was named by 'Forbes' magazine this year as the third most powerful celebrity in the world.
Bieber seems to be doing OK -- at least publicly. On the red carpet of Wednesday's Victoria's Secret fashion show he said, "I'd rather be here than anywhere in the world."
