Hollywood Singer and Rapper Chris Brown is being claimed for hounding by a fan. Reportedly, alleged identified as Marq Stevenson, who attended the 27 year old singer's concert in Dallas last year, sued that Brown's staff bullied him and stole his hat after he tried to get the star to sign it. Stevenson wants USD 2,500 for the alleged bullying, USD 25 for the hat and USD 225 for his concert ticket. He claims he handed the hat over to get signed but it was never returned to him. Earlier, Brown also charged by Nia Guzman, the mother of his two year old daughter Royalty, recently confessed she "can't say anything positive" about co-parenting with him.
