She's known for her wacky sense of humour, and is never afraid to poke fun at her catwalk queen status.

And Cara Delevingne did her best to stand out among the effortlessly cool jet-set crowd as she soaked up the sun in Barbados on Friday.

Ditching her chic shades in favour of a pair of hilarious oversized comedy suglasses, the 21-year-old supermodel's choice of beach accessory wasn't exactly runway ready.

Goofing around as she posed for photographs on the beach at Heron Bay with her friends and family, the willowy beauty seemed to be having a whale of a time as she soaked up the sun on the Caribbean island.

Showcasing her slim model figure in a tiny scarlet bikini, the model of the moment put the stresses of the past year behind her as she enjoyed a day of fun in the sun with her nearest and dearest.

After a spot of sunbathing on the pristine white sands, Cara threw on a pair of denim Daisy Dukes and one of her signature burgundy backwards caps and headed onto a yacht, where she was seen chatting absent-mindedly on her mobile phone.

Displaying her naturally flawless skin, the London-born catwalk queen went make-up free and wore her ash blonde locks hanging in wet tendrils down her back as she enjoyed her day out at the beach.

And it would seem Cara was somewhat enamoured with the sun-soaked Caribbean, posting a picturesque snap on her Twitter page alongside the caption: 'How could I ever leave? #barbados.'

Cara and her family arrived in the sun-soaked holiday hotspot earlier this week as they prepared to spend the festive break together during a rare break in the model's usually jam-packed schedule.

While the sun failed to shine on the island on Boxing Day, nothing was going to stop the runway goddess from letting her hair down.

The 21-year-old gamely tried her hand at wakeboarding after taking to the choppy waters, but her efforts were left wanting.

Cara had traded the blue, equine print two-piece she wore earlier that day for as striking red bikini, over which she wore the obligatory life-jacket for an amateur attempt at the surface water sport.

Despite managing to keep her balance, the young model repeatedly crashed into the water whenever her boat gained momentum.

At one point she almost lost her bikini bottoms, which rode down her slender thighs as she doggedly pulled herself onto the wakeboard for another attempt. 

But the star was nothing if not determined.

Cara was joined by older sister Poppy, and the two girls were spotted giggling away as they precariously attempted to balance on the board with a female pal.

With the weather decidedly overcast, Poppy had tweeted a picture of the unseasonably grey conditions earlier that day with the accompanying caption: ‘Someone’s in a mood today #CheerUpBarbados.’

Earlier that day Cara revealed what appeared to be a new tattoo on her chest after hitting the beach close to her exclusive digs at the island's Heron Bay resort.
