Ex-�American Idol� Fantasia Barrino encountered a racist, threatening letter while going through fan mail last night, TMZ reported.
Barrino�s manager told the gossip site that following the singer�s �Color Purple� performance at Pantages Theater in Los Angeles, Barrino opened up a letter filled with racial slurs while in her dressing room.

The letter writer claimed to have worked as a security guard when Barrino was a season three �Idol� contestant and called for her to �go back where you came from and die,� according to TMZ.
An alarmed Barrino immediately contacted theater security, who then called the cops, her manager said.
