Rihanna has split from long-term boyfriend Matt Kemp, it has been revealed.

But rather than moping around in her bedroom, the 22-year-old R&B princess has been flaunting her curves in a tiny bikini while on holiday in Barbados instead.

A friend of the singer told Us Weekly magazine: "It happened over the last few weeks. She basically was just over it."

Rihanna and baseball star Kemp started dating last December, but she has admitted that it was proving hard to make a long-distance relationship work - because they both had such busy work schedules.

Ri-Ri is spending the festive break in her home country of Barbados and seems to have been having a whale of a time sunning herself on the beach, jet-skiing and laughing with her pals.

We've no word on Matt though, so presumably he is moping in his bedroom. We know we would be!
