R+B superstar Rihanna has scuppered rumours she is dating singer Chris Brown - stating she is having too much fun living the single life to have a boyfriend. The Umbrella star has been linked with a whole host of male stars - including music mogul and rival diva Beyonce Knowles' partner Jay-Z, who produced her smash hit record. However, the 20-year-old Bajan beauty denies she is dating anyone at the moment, but states if a "good guy" came along she would reconsider her current single status. She says, "Rumours come with the territory and you can't help these things. "I'm single. If a good guy comes along we'll make it work, but for now I'm having fun being a single woman."
