Concerned fans of Britney Spears have started up a website, urging the singer to divorce her husband Kevin Federline.

Last week (ends09DEC05), speculation mounted that the TOXIC singer's 15-month marriage to Federline was over, after the unemployed dancer's Ferrari was towed away from the couple's Malibu, California, home.

Spears, who gave birth to the couple's son Sean Preston in September (05), pulled out of a Billboard Awards appearance on Tuesday (06DEC05), leaving Federline to fly to Las Vegas, Nevada, alone.

Worried devotees of the singer have created DivorceKevin.com, which includes a petition for Spears to divorce her husband.

A statement on the website reads, "Welcome to the home of the anti-Kevin movement. Are you sick of seeing the train wreck that is Britney and Kevin? Sign the K-Fed Up Petition, grab your Divorce Kevin gear and help Britney remove the boil that is Kevin from herself and her payroll!"
