Rihanna has taken up belly dancing.

The 'California King Bed' hitmaker is being given lessons in the exotic art by a professional dancer from Mexico in a bid to keep in shape - and friends would not be surprised to see some of her new moves turn up on the European leg of the singer's 'Loud' tour in September.

We shouldn't be surprised to see a little of this influence when Rihanna goes on tour later this year.

A pal of the Bajan beauty told the Daily Mirror newspaper: "She loves belly dancing and has been getting all her dancers to join in. They've even had a few private Arabian-themed parties.

"We shouldn't be surprised to see a little of this influence when Rihanna goes on tour later this year."

Belly dancing appears to be a more conventional way for the 23-year-old singer to keep fit, but Rihanna - who is currently on her 'Loud' tour in the US - has previously revealed she stays in shape by "walking for miles" through airports when she is going from place to place playing gigs.

She said: "I keep fit by walking through so many airports. You end up walking for miles in those places!"

Rihanna also has another reason for getting fit because she is looking for a man, recently explaining she wants a guy who will "earn" her love.

She added: "I'm open to love. But guys should have to earn it. Because the minute they get it, they want something else.

"Men are like hunters; they like the chase. So you have to keep 'em guessing. Actually, I'm like that too. I get bored quickly. So if someone can make me laugh, that's the best."
