Rihanna gets NAKED for Movie Kangz Magazine

She's been inundating her fans with pictures of her luxury holiday in Sardinia and the surrounding areas this week.

And while Rihanna has so far shared a number of candid images of her in bikinis and various holiday outfits, her latest pictures could be the most revealing yet.

The Umbrella hitmaker has taken to her Instagram page to show off her impressive physique for all to see.

She poses pushing her pert derriere in the air while she wears animal print bikini bottoms with a mismatching zig-zag top.

Rihanna wears her hair in long plaits as she strikes the sultry pose.

And in another picture she wears some other floral bikini bottoms but appears to be topless as she faces her back to the camera while her friends look forward.

She is joined by six girl pals aboard her luxury boat as they continue to sail around in the sun.

The bikini clad bevy of girls all pose up for the picture, while Rihanna smoulders looking over her shoulder as she reveals her naked back.

Rihanna also showed off yet another bikini outfit this morning as she looked into the camera lens with a strapless orange bikini, while she wore white-rimmed shades.

She can also be seen enjoying the sunset as she looks into the distance while the yacht sails along the water.

The night before the singer was forced to compromise her outfit when she climbed back aboard her luxury yacht following dinner in Positano, on the Amalfi Coast.

She had been wearing a pair of towering white platform shoes for her night out, but slipped them off to get back on the boat.

Enormous heels and the 24-year-old's known penchant for enjoying a tipple or two of an evening are not the best combination, and could have ended in tears - or overboard.

Rihanna teamed her white platforms with a bright red and white patterned jumpsuit with a keyhole neckline.

She has been wearing her in long, wild curls during her European holiday.

Sail away with me: Rihanna and her entourage have been touring Italy

The Where Have You Been singer and her group of girlfriends have been touring Italy, stopping off in Sardinia and Capri before Positano.

She is staying aboard a luxurious vessel, and has been making fans green with envy by tweeting pictures of the gorgeous interior.

Rihanna was also seen enjoying some water sports the day before in Capri, zooming across the sea on a motorboat-led raft.

Later, she was spotted dancing up a storm on the deck of the boat alone.

Rihanna told fans on Twitter that she hit the nightclubs in town that night, but the music wasn't to her liking.

'Music was a lil rough in the club lastnight! Solution: walk off on the dance floor,' she tweeted.
