Rihanna fans to protest Brown

Friday the 13th is going to be a tough day for troubled R&B star Chris Brown - angry Rihanna fans are staging a protest in New York, where the R&B star's posters will be ripped up and CDs shredded.

Thousands of Rihanna devotees are expected to take part in the pre-St Valentine's Day protest, arranged by radio station WBLI and the wounded singer's fan club officials.
