British singer Amy Winehouse will not be performing at the Coachella festival in California due to "current legal issues," says her spokesman, Chris Goodman.

Winehouse was charged with assault last week for allegedly attacking a fan at the End of Summer Ball, a £700 ($1,275 Cdn) a ticket fundraising concert in London on Sept. 26, 2008.

She is due back in court on March 17.

Sherene Flash alleges she was hit in the eye by Winehouse after asking to take a picture.

Goodman would only say Winehouse's "legal case would not be sorted out in time for her to make the music fest."

He declined to confirm whether she was denied a visa because of her court case.

The 25-year-old performer was due to hit the stage April 19 at the annual festival in Indio, Calif.

Winehouse has had a public battle with drug addiction and frequent run-ins with the law. And, in January, her husband, Blake Fielder-Civil, began divorce proceedings against her.

Last year, the U.S. government declined to give her a visa to attend the Grammy Awards in 2008. The decision was later reversed, but it came too late for her to go.

Her album Back to Black captured five Grammys including best pop vocal album and song of the year for Rehab.
