Meanwhile reports today suggest that Rihanna’s new boyfriend Matt Kemp (the one the was recently spotted smooching while on a yacht) has a violent past – which is the last thing she needs following her abusive relationship with her ex-boyfriend Chris Brown.

An ex-girlfriend of the LA Dodgers star, 30-year-old actress Felisha Terrell, has described Matt as “violent and abusive” and claims she took out a restraining order against him in June 2008.

“He is violent and I am afraid. He is threatening to take all the items I purchased and try to destroy my property,” she said.

“He brings his friends driving up and down the street to try and intimidate me. I am very fearful. He has other people calling me and stalking me.”

A spokesperson for Matt has since strenuously denied Felisha’s claims adding that the LA dodgers star is in fact a “consummate Midwestern gentleman who has never displayed any act of violence towards a woman."
