Rihanna - Rihanna Blames 'Traffic Problem' For Cancellation

RIHANNA has blamed her no-show at the Grammy Awards on a traffic mishap, according to reports.The Umbrella hitmaker was due to perform at the annual awards show in Los Angeles on Sunday night (08Feb09).

But she cancelled after her R&B singer boyfriend Chris Brown was arrested over an alleged domestic violence felony battery.

Some reports in the U.S. are now suggesting Rihanna was involved in the alleged incident - but her spokeswoman insists the singer was caught up in an unspecified traffic problem, according to E! Online.

Brown, 19, was booked for making criminal threats and freed on $50,000 (£34,250) bail after L.A. cops received a 911 call in the early hours of Sunday morning.

It followed an incident in which Brown and an unidentified woman were involved in a heated row in a vehicle in Los Angeles following music mogul Clive Davis' pre-Grammy Awards party on Saturday (07Feb09) night.
