Rihanna And Matt Kemp Break Up

Source cites Rihanna's busy schedule as a cause for the split.

Rihanna and Matt Kemp kicked off 2010 as a couple, but it seems they are bidding the year farewell apart. According to Us Weekly, the singer and her baseball-player beau have split.

“It happened over the last few weeks,” a source told the magazine. “She basically was just over it.” The insider added that the pop star has been “so busy” with work that “he just can’t keep up with her crazy travel schedule.”

The duo started dating in January and couldn’t keep their relationship under wraps for long, but apparently Kemp got tired of dating a woman with a jet-setting lifestyle. “Matt’s sick of always following after her like a puppy dog all over the world. He wants something more normal,” the source explained. “It was never as serious as it looked. It was always just [about] having fun.”

Shortly after they began dating, Kemp threw Rihanna a birthday party in February.

In June, Rihanna opened up about the L.A. Dodger to Elle magazine: “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.”

In November, when she released her latest album, Loud, Rihanna said that her athlete boyfriend enjoyed hearing her softer side on the record. “He really likes, actually, the ballads on the album. Those are his favorite ones,” she said. “I always play him songs when I finish them. I’ll bring them back home and ask him what he thinks. At the end of the day, we still disagree on some things, but for the most part … he loves everything on the album. … ‘Who’s That Chick,’ he doesn’t really like that one. I guess it’s too lightweight pop for him.”
