US publication Star Magazine has heaped further misery on the stunning R&B star by claiming she fears her estranged boyfriend CHRIS BROWN could release a steamy home video the couple allegedly made together. A source who approached the magazine said: “They’ve had tons of crazy nights in bed, and Chris has recorded many of them…They both have very kinky sides.” It’s also claimed that Rihanna enjoys role-playing and dressing up as a dominatrix and that she is allegedly worried Chris could put the footage out there for the world to see. The source went on to say: “Rihanna has no issues with her sexuality. But she’d be mortified if her friends and family found this out! “This whole beating incident is terribly humiliating for her. She’s already traumatized and will do anything to make it all go away as quickly as possible.“The last thing in the world Rihanna wants is to see herself in the sex videos all over the Internet! She’s an intensely private person.” Brown, who’s kept a low profile since their alleged fight, was seen yesterday seen at an airport in Richmond, Virginia, riding a BMX around his luggage on the runway.
