Smooth guy of RNB Chris Brown has denied the rumours that he is dating Umbrella star Rihanna, commenting that he is “definitely single”. It was only a few weeks ago that the twosome were snapped getting cosy in various nightclubs around London, and were even seen canoodling in the pool whilst on holiday in Jamaica last month. Brown, who is currently in the UK promoting his new Album Xclusive, is said to be fed up with the accusations. Something tells me he wants to appear single so he doesn’t go breaking all those young girls’ hearts!
