PIX: Bikini-clad Rihanna holidays with friends

Pop diva Rihanna, who is known to take off for frequent vacations to exotic locales with her gal pals, jetted off to the island of Sardinia in the Mediterranean sea for a break with her entourage.

Rihanna's friend Melissa Forde, who accompanied her, posted pictures on her Twitter account.

Rihanna looks curvier than her earlier avatar from her Hawaiian holiday as she pouts for the camera.

The group spent almost all of the vacation on a luxury yacht sipping cocktails and lounging around.

Rihanna sported a green bikini and bright red lipstick as she flaunted her new curves and tattoos.

The Talk That Talk hitmaker jetted into Sardinia over the weekend following a break in her native Barbados.

She was in her hometown to attend the funeral of her grandmother Dolly, who passed away earlier this month following a battle with cancer.

Staying on the luxury boat that's just off the coast, Rihanna is making the most of her vacation.

Rapper Drake is rumoured to be joining the singer soon.
