Rihanna has a new boyfriend and he keeps her "sane".

The Barbadian R&B singer has been going out with baseball star Matt Kemp since the beginning of the year. She says that the time she spends with the Dodgers outfielder keeps her calm despite the stresses of her frenzied lifestyle.

"I have a boyfriend. I'm so happy. I feel really comfortable, and it's so easy. I have such a chaotic life, but at the end of the day, that is just my peace. It keeps me sane, really, talking to him and talking to my family," she said.

Rihanna also spoke of her "confusion" in the aftermath of the Chris Brown incident in February 2009 because she couldn't believe that her "best friend" could turn on her.

"A year ago, I was very confused. Because he was my best friend," she told US magazine Elle.

"All of a sudden, one night changed our whole lives-not only our friendship, but our lives.

"I wanted to wake up one day and just not have that pain anymore. I wanted to be with him again or get over him-it was either-or. I just didn't want to feel the pain, the confusion."
