The singer will be performing live in the capital this evening along with Jay-Z, Beyonce, Bono and The Edge to raise funds for the victims of the Haiti earthquake.

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."
