[Hollywood News]: London, Dec 21 : R&B artist Usher has split from his girlfriend of three months, supermodel Naomi Campbell, after she refused to accompany him to the Billboard Music Awards earlier this month.

Usher who won 11 awards at the ceremony was reportedly very angry when Campbell declined his invitation to go with him to Los Angeles where the ceremony was taking place, reports the Mirror.

"Things came to a head at the Billboard Awards when she told him she wasn't going to go with him and he got all tetchy with her. He went in by a back door. That probably wouldn't have happened if Naomi had been there," the report quoted an insider as saying. (ANI)
