Allen 'Dropped From Mtv Awards'

British pop star Lily Allen has reportedly been dropped from the Mtv Music Video Awards following her recent U.s. visa problems.

The Smile singer, 22, was detained by customs and immigration officials in Los Angeles earlier this month after flying in from Australia for the Mtv Video Music Awards nominations party.

Officials were reportedly interested in Allen's March arrest in London following an alleged altercation with a photographer. She was cautioned for the incident after voluntarily attending a police station in June.

British newspaper the Daily Mirror reports Allen's recent problems entering the U.s. have lead them to cancel her planned performance with Kanye West and Common at the Las Vegas ceremony on September 9th.

A source says, "MTV were desperate to get Lily and they're furious with her visa situation. They've decided to pull the plug because they didn't want to leave it to the last minute to find out if she could or couldn't make it."

Allen is reportedly consulting lawyers to find out why her U.s. visa was revoked.
