Certainly not shy! Heidi Klum and her hunky beau Vito Schnabel proved things are as steamy as ever as they packed on the PDA during a romantic trip to St Barts on Wednesday

The good-looking duo could hardly keep their hands off one another as they hit the surf, each showing off their fantastic physiques - both the result of gruelling hours in the gym no doubt. 

Heidi proved exactly why she is one of the world's leading supermodels as she smouldered in her barely-there bikini, comprising of a tiny triangle crop top and minuscule bottoms which made the most of her pert derriere. 

The German-born beauty showed off her incredible stomach, which boasted rippling abs while her ample bosom was encased in her bust-enhancing bikini top. 

While her bikini was simple in style, she allowed her incredible body to do the talking as she showed off every inch of her incredible curves. 

Great from every angle: The 42-year-old supermodel showed off her age defying figure in a tiny snakeskin bikini, which she later accompanied with a snorkel and flippers, while Vito, 29, showed off his fit physique in a pair of turquoise swimming shorts

When it comes to holidays, Heidi Klum doesn't do things by halves.

The supermodel is currently living it up in the Caribbean, and whilst we'd all love to jet off and join her, buying a bikini like hers is definitely a cheaper way to banish our holiday blues!

She soaked up some sun wearing an itsy bitsy python print two-piece. We love the classic triangle style, plus the gold metal accents add an extra bit of va va voom. The supermodel is launching her very own swimwear line, so perhaps it's a sneak peak of that, and if so we can wait to see the rest!

Snakeskin is a great way to take a walk on the wild side without going all out for leopard print. Simply style yours with tousled hair and oversized sunnies for the ultimate in beach chic.

So with that in mind, get a piece of the python pie by shopping the options we've got lined up for you in the edit below. But the Melissa Odabash version (click right) is top of our wish list.

Take my hand... The mother-of-four shares daughters Helene, 11, and six-year-old Lou, and sons Henry, 10, and nine-year-old Johan with ex-husband Seal - yet she showed no signs of child baring on her incredible figure.

Lucky guy! Heidi looked as though she could hardly resist her hunky man as she cosied up to him on the stunning beach 

Far from lying on the sand all day, she threw herself into beach activities by slipping on goggles, a snorkel and a bright yellow pair of flippers, prepping herself for her dip in the exquisite waters during the sun-soaked day on the surf. 

Her long blonde tresses cascaded down her back before she pulled her locks into a bun, keeping her hair out of her face as she got ready to throw herself back into the waters. 

While dipping in the sea, it was Heidi who opted to snorkel, while Vito merely bobbed along beside her, seemingly happy to be spending some downtime with his beautiful girlfriend.

In you go! The idyllic waters were simply envy-inducing as she was spied going shoulder deep in the waters

Heidi proved her attention to her beauty regime, as she slicked on a perfect purple manicure while stacking on a gold rings to give the look a boho beach babe feel.

Hand in hand: Proving themselves to be true romantics, the pair walked along the beach hand in hand

The couple that snorkels together... Vito and Heidi enjoyed the exquisite waters while looking into the sea via their snorkels 

Got something up your nose? Heidi appeared to have inhaled some of the water and struggled to keep her cool 

Come here! Heidi could barely keep her hands off her man as they splashed around together in the Caribbean waters 

Having a whale of a time: While Heidi remains relatively tight-lipped about her love with Vito, she proved actions speak louder than words as she continually kissed her hunky man while they enjoyed their trip ashore

Splash-tastic: Heidi wiped the water off her face, going make-up free and showing off her ageless complexion on the shores

While Heidi remains relatively tight-lipped about her love with Vito, she proved actions speak louder than words as she continually kissed her hunky man while they enjoyed their trip ashore. 

Back in February, she made a public declaration of her adoration for her boyfriend of two years when she shared an intimate selfie of the pair withher 2.6million Instagram followers, before captioning the shot: 'I love you'.

Holding on: While Heidi remains relatively tight-lipped about her love with Vito, she proved actions speak louder than words as she continually kissed her hunky man while they enjoyed their trip ashore

Pure shores: Heidi marked her territory on the shores by plonking down the duo's belongings including sunglasses and shoes, before they ventured into the waters for their scuba diving fun

Holding on: Heidi's long legs went on and on while her pert derriere looked simply sensational in the tiny two-piece

Wowing the beach: Her long legs, lithe limbs and flat stomach were envy inducing, particularly given her Quadragenarian status 

Detailing her various methods of staying in shape, Heidi said: 'If it's with my kids or we’re going on a hike with the dogs or jumping in the swimming pool, or we have a gigantic trampoline in the backyard. Every once in a while I go on the treadmill, but I don’t love that so much. I like the outdoors a lot.'

The America's Got Talent judge also loves jogging in New York because she gets inspired by other athletes.

'Especially in New York City I run on the West Side Highway because I get really inspired when I see other people running. It is packed with people running. If you go every day you recognise people and you’re like, “Oh my gosh, it’s this person and this person.” 

Having a dip: The duo splashed around in the shores looking blissfully happy 

Strutting her stuff: Clutching her flippers, Heidi strutted out of the sea - treating the beach like her very own catwalk 

Envy-inducing: Heidi's body was incredibly toned, as she revealed her stunning curves and honed physique 

Having a dip: Heidi was just as stunning as the scenery surrounding her yet there is no doubt she stole the show 

'Everyone kind of comes early in the morning at the same time and they kind of keep me going because if they can do it, I can do it too. The metabolism definitely changes when you turn 40. I always thought, That’s not going to happen to me, but it is happening to me.

'If I indulge more, I have to exercise more. I figured out what works for me. I'll eat everything but the pasta and bread. Do I want the pasta? I do. But I choose not to eat it.'

However, she does treat herself from time to time, Heidi added: '[I was] out to dinner this weekend, and truffles are in season. I had to have the truffle pizza and the truffle pasta. It's not like I don't [indulge], but not all the time. My mom fries everything and drenches it in cream sauce. Anytime she comes to visit, it's like—boom!—two pounds [for me].' 

In tip-top shape: Detailing her various methods of staying in shape, Heidi said: 'If it's with my kids or we’re going on a hike with the dogs or jumping in the swimming pool, or we have a gigantic trampoline in the backyard'

Up close and personal: Back in February, she made a public declaration of her adoration for her boyfriend of two years when she shared an intimate selfie of the pair withher 2.6million Instagram followers, before captioning the shot: 'I love you'
