Rihanna is still good friends with ex-boyfriend Matt Kemp. The baseball star and the 'California King Bed singer split last December after an 11-month romance but the handsome athlete says they have a good relationship and are still supportive of each other. He told Us Weekly magazine: Shes a good friend of mine. Were good. Theres no bad blood between us. Weve all got busy lives and were working on our careers and concentrating on our careers. Like I said, I wish her all the best of luck and she wishes me all the best of luck. Rihanna and Matt split because they were struggling to find the time to see each other and the Barbados-born beauty had admitted they were feeling the pressure of making a long distance romance work.EPS
