Rihanna and Matt Kemp Call It Quits

Time for Rihanna to pen a new break-up ballad: After almost a year together, she and Matt Kemp have called it quits, an insider close to the singer tells Us Magazine.

"It happened over the last few weeks," explains the source. "She basically was just over it."

A rep for Rihanna (she's currently vacationing with family in her native Barbados) could not be reached for comment.

Los Angeles Dodgers outfielder Kemp, 26, helped Rihanna, 22, move on from Chris Brown, who infamously assaulted her in February 2009. The duo were first spotted frolicking together in Cabo San Lucas last January, and slowly opened up about their romance in the spring.

But the "Only Girl" singer has been "so busy," the insider says. "He just can't keep up with her crazy travel schedule."

"Matt's sick of always following after her like a puppy dog all over the world. He wants something more normal," the source adds.

Plus, the insider says, "It was never as serious as it looked. It was always just [about] having fun."

Stilll, back in May, Kemp gushed about his love: "She's just a fun person. I love to be around her."

In June, Rihanna similarly said of Kemp: "I'm so happy. I feel really comfortable and it's so easy. [The relationship] is just my peace. It keeps me sane."

Rihanna: I "Could Be" Pregnant By Next Year

Is Rihanna ready for a mini-me?

In the December issue of Interview, the 22-year-old "What's My Name" singer hints that motherhood may soon be on the horizon.

"I don't really plan on the age. It could be a year from now. It could be 10 years from now. Whenever is right," Rihanna tells the mag. "I mean, I have a lot of other stuff to accomplish before I get to kids. Whenever the time is right, I'll just know."

This much is certain: the pop star, who began dating L.A. Dodgers center fielder Matt Kemp in January, wants an all-male household.

"If I had a girl, she'd probably be really rebellious," the singer laughs. "She would be like a bundle of karma."

As for where she would raise her brood, Rihanna says she "would love to bring them up in Barbados," though her job may prevent that from becoming a reality.

"I can't live that far away from everything now, without kids," she explains. "So I certainly couldn't raise kids and [have a career] with the demanding schedule that I have."
