Wet and Wild! Cara Delevingne wears fun eye-print string bikini as she zips through the air on a rubber ring while holidaying with new BFF Rihanna

She's enjoying the kind of holiday most girls will go their entire lives dreaming of.
But Cara Delevingne decided that instead of kicking back and enjoying the delights of her £300,000 super-yacht, she would throw herself into a range of high-octane activities.
The 20-year-old model was kicking back on board a lavish vessel with her new showbiz bestie, Rihanna, which the pair are believed to have hired for two weeks as part of a lavish half a million pound holiday.

The model of the moment clung to the ring for dear life as she was pulled along by a speedboat

Rather than soak up the sun on the luxury boat and allowing her minions to cater to her every whim, the fun-loving starlet decided a spot of playtime was well and truly in order.
Showing off her playful side in a fun eye-print string bikini, the British beauty joined the Diamonds hitmaker as they whizzed around the Riviera on huge rubber rings.
Grinning with delight as they zipped through the air, the pair looked like any other 20-somethings enjoying themselves on a girlie holiday, rather than two of the world's most-famous women.

And the larks continued when back on-board their lavish yacht, with Cara boogying up a storm alongside a mystery man, who she later gave a playful slap on the bottom.
The model of the moment looked the picture of happiness as she danced under an outdoor shower, before posing for pictures alongside her pals.
While Cara opted for playful beach attire, Rihanna chose a sexier swimsuit, showing off her incredible figure in a plunging black one-piece as she soaked up the sun in the South of France.

The two girls have become firm friends in the past few months after first partying together at London Fashion Week in March.
And it could be that Cara has a 'wifey'-shaped hole in her life of late following her reported fall-out with former BFF and Rihanna doppelganger, Rita Ora.
It's claimed the pair had words following an embarrassing incident where Cara crashed the stage during Rita's performance at a DKNY fashion party last month.

Cara Delevingne is a fan of this collaboration between Kesh and American Apparel. She wore the eye print T-shirt last week and now she's wearing the bikini while on a boat with Rihanna. It's only £56 and is available to buy now so if you want to look like the model of the moment then now's your chance.

Kesh is an LA based artist and her designs for American Apparel adorn T-shirts, dresses, cropped tops, leggings, men's underwear and hats and Cara is clearly fond of this eye print in particular. Eyes are going to be big this autumn with super cool French label Kenzo making them their AW/13 motif. Trust Cara to get a head start.

Graphic prints are everywhere this season and that includes beachwear. If you're bored of florals, stripes, and block colour then try a geometric design to shake up your holiday wardrobe. We've selected our top picks below.

The pair, who were so close that they used to call each other 'wifey', haven't been seen together since that evening - when Cara left the audience cringing with her dance moves and singing attempts.

A source told MailOnline at the time: 'It was a bit of an embarrassing spectacle. She was singing massively out of key and lots of people looked uncomfortable - it was like watching a car crash.
'Rita tried to take the microphone back a couple of times before succeeding, only for Cara to snatch it off her again and carry on singing out of tune.'

Anything you can do: Cara then appeared to be returning the favour and washing her friend's hair

And even though the pair have both attended the same events in recent weeks, including the Glastonbury music festival, they have not been pictured together.
A source told the Daily Mirror: 'There’s a lot of hurt on both sides but Rita’s been working towards her singing career and carefully crafting her image for four years and it was all in danger of being a joke after that shabby performance.
'Rita’s been advised to distance herself from the model.'

New pals: Rihanna and Cara have become particularly close friends in recent weeks

Reports of the feud were furthered even more when Rita referred to her designer friend Stella McCartney as her 'new wifey' in a post on Twitter.
In addition to blowing £300,000 on their super-yacht, Cara and Rihanna have £200,000 set aside for restaurant and nightclub bills, and will follow the fortnight with a long weekend in Barbados to recuperate.
But until then they look set to party as hard as they can, as they cruise along the Mediterranean coastline on board a mega yacht.

Singer Rihanna, 25, appeared to be showing Delevingne, 20, the correct technique for chasing the shot with a segment of lemon and the model was rarely to be seen without a drink on her hand.
Photographs of the young stars aboard their party boat emerged just days after it transpired that Cara had struck up a friendship with troubled rock star Pete Doherty, a former boyfriend of Kate Moss.

Cuddle time: The singer also seemed to be close to Cara's new pal, and was seen treating him to a huge hug

The model of the moment, whose raucous lifestyle has earned her the nickname the ‘new Kate Moss’, has hinted in the past that she would like to move into the music industry.
And Doherty, formerly of indie band The Libertines, is said to have become ‘besotted’ by her since meeting her in February. 
A source told a fashion magazine: ‘Pete thought Cara was amazing and so beautiful. Afterwards, he asked a friend to pass on a message and his number. Everyone was a bit unsure about it - he’s certainly got a bad-boy reputation - but he was really insistent.
‘Cara took ages to reply, but she’s a big Libertines fan, so once she did get in touch, they talked about his days with the band.

In her element: Cara looked positively tickled pink as she giggled away at one of her friends as he larked around on deck

Comfort zone: The model looked perfectly at ease as she got dressed on board the yacht

‘Cara plays the drums, so Pete invited her round to his house in Wiltshire to play together.’
News of the pairing comes within weeks of Cara,  who is the face of British brands Burberry and Mulberry, being spotted dropping a suspect-looking bag of white powder outside her home in Belgravia, London.

Photographs of the incident added to growing concern about the young model’s health, after she was seen falling down some steps after a night out during London Fashion Week.
And her rumoured friendship with Doherty is just the latest cause for alarm.

Cara Delevingne and Rihanna have reportedly spent £300,000 on hiring a super-yacht to ferry them around the French Riviera

The pair, who have developed a close friendship in recent months, will follow the fortnight with a long weekend in Barbados to recuperateThe source added: ‘It’ll be a disaster for Cara if she hooks up with Pete. Cara’s mum - a recovering heroin addict herself - and sisters must be furious about it.
‘They’re bound to be worried about her constant partying and Pete’s not exactly clean living.’ 
It was during Fashion Week that Delevingne secured her friendship with Rihanna, 25, joining her to celebrate the launch of her River Island clothing range.

Meanwhile Rihanna lounged on inflatables and smoked what looked to be an electronic cigarette

The singer encouraged Delevingne to get her first tattoo, a lion’s head on her finger, and she has since gone on to have the letters CJD inked on her forearm.
This weekend, she appeared to have added a third to her collection after Tweeting a picture of the words ‘Made In England’ written on the sole of her foot.
Last month, a source said of her upcoming holiday with Rihanna: ‘They’re going to rent a yacht in the South of France, when Rihanna has a two-week break in her tour, and then fly out to the Caribbean.

The new best friends appear to be making the most of their break away together, with both drinking shots aboard the luxury yacht

‘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. 
‘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.’
