She may have a line of men waiting to get next to her, but the only jealous lover in Rihanna’s life these days is her demanding work schedule. The singer, who split from baseball player Matt Kemp earlier this year, tells Ellen DeGeneres, “My personal life is pretty much non-existent, which is not good, not for the long run.… That’s why I stay on Twitter a lot. So I can conversate [sic] with my fans. Because I don’t get any booty calls.”

Despite rumors last month that she was linked with British boxer Dudley O’Shaughnessy (who appeared in her “We Found Love” video), the island beauty insists she’s totally single. “I’m not dating anyone right now. I’m not dating at all,” but adds, “I’m not necessarily happy being single. It’s not really that cool.”

What kind of man would it take to win one of the most desirable woman on the planet? A bold one. She explains, “I can’t have guys that are intimidated by me.… I like men that are more aggressive but mysterious but I like a man to be very sure. I like them to be sure of themselves.”

“I’m the lady and the only way for us to make this work is for us to play our roles. You know, I can’t really be the man for you. I don’t want to have to be. I’m the man at work all the time.”
