Rihannaand model Cara Delevingne are reportedly planning a £500,000 holiday to the French Riviera in August.

According to The Sun, the Burberry clothes horse will swap 'wifey' Rita Ora for RiRi, with the pair already splashing out £300k to hire a superyacht for their two week trip.

It is thought that the pals have set aside an extra £200,000 to cover club and restaurant costs, and after their epic girls holiday, will fly to Rihanna's native Barbados for the weekend.

An insider told the tabloid: "Cara and Rihanna have booked the holiday after agreeing they don’t need men in their lives to have fun.

“They’re going to rent a yacht in the south of France at the end of August, when Rihanna has a two-week break in her tour, and then fly out to the Caribbean.

“It will be no-holds barred and they’re spending more than half a million on the yacht rental and on going to top clubs and restaurants."

The source added: “It’ll be non-stop booze and they are already saying they’re not going to get much sleep — maybe a couple of hours each night.

“They plan to relax when they get to Barbados.”
