Heidi Klum flaunts bikini body in skimpy two piece as she cuddles up to husband Tom Kaulitz in St Bart's

Heidi Klum flaunted her sculpted bikini body as she continued her sun-kissed St Bart's vacation with her husband Tom Kaulitz.

The 51-year-old supermodel and the dashing 35-year-old guitarist, who both hail from Germany, have been married since 2019.

When they were spotted on the beach this Tuesday, they appeared as smitten with each other as they were in the first flush of their romance.

They sweetly held hands with each other as they sauntered into the ocean together, and they could be seen cuddling up to each other as the lounged on the sand.

For her latest day in the sun, Heidi demonstrated her supermodel credentials in a barely-there two-piece that displayed her statuesque figure to full advantage.

She showed off her enviably taut midriff and vertiginous legs, letting her luxurious blonde mane fly free in the sea breeze.

Heidi, who grew up in West Germany, accessorized the look with a gleaming pair of shades and added a touch of glitz with a medallion necklace.

She could be seen beaming at her husband as the pair of them enjoyed a chat, strolling hand in hand into the shallows together.

At one stage she decided to warm up by pulling on a print blouse-trouser combo that resembled pajamas, teamed with a straw hat and Gucci shawl.

Meanwhile Tom, a drummer for the band Tokio Hotel, went shirtless with a set of swimming trunks, catching plenty of sun as he enjoyed the Caribbean climes.

Last Wednesday, as Tom and Heidi holidayed in St Bart's, his identical twin brother Bill was evacuated from his home amid the catastrophic Los Angeles fires.

Bill, who is one of Tom's bandmates in Tokio Hotel, posted a photo of his packed belongings to social media and wrote: 'Evacuated.'

Meanwhile Heidi and Tom live at a $9.875 million mansion in Los Angeles' upscale Bel Air neighborhood, which has so far escaped the fires unscathed. 

Heidi co-parents four children with her ex-husband Seal - her daughters Leni, 20, and Lou, 15, as well as her sons Henry, 19, and Johan, 18.

She had her three younger children by Seal, who also adopted Leni, the product of Heidi's dalliance with Italian businessman Flavio Briatore. 

A couple of years ago Heidi reflected on the fact that her current husband is a quarter of a century younger than she is - a fact that has drawn plenty of online scrutiny.

'I'm 50 and no longer 20. I'm not a young girl who hasn't experienced anything yet or has no idea about life,' she acknowledged to Glamour UK in 2023.

'Time won't stand still for me and Tom will never catch up with me. I'll always be 16 years older, and I'm aware of that,' Heidi continued.

'I know that I will look older than him sooner. Maybe it will be a problem for me in 10 years' time, maybe he won't like it then,' she reflected.

'In 20 years, I'll be 70. I usually plan for the future – but with my husband, I live in the here and now,' the Teutonic blonde shared.

Heidi waxed rhapsodic about her marriage to Tom in an interview conducted just a few months after they secretly exchanged vows in California.

'I’m just a much happier person,' she said. 'For the first time, I have a partner who I can discuss everything with. Someone who shares duties that we all have in our life.'

She explained: 'I used to be on my own with everything. For the first time, I get to experience what it is actually like to have a partner,' via People. 

The year before they got married, Heidi reflected on her bond with Tom and mused: 'Maybe it is because he is German and we understand each other in a different way.' 

Leni has followed her mother's footsteps into modeling, and Heidi has gotten brickbats online for posing with her daughter in lingerie shoots for Intimissimi.

Heidi recently shared that both of her daughters have started sampling items from her wardrobe, much to their mother's delight.

'I get so excited when I see my daughters re-wearing my clothes,' Heidi said while attending Prince William's Earthshot Prize Awards in Cape Town in November.

'My eldest daughter, she also is a model, and she goes to events and when she wears my clothes I’m not just proud but we can upcycle,' she told People.

A few year's ago Heidi's nutritionist Oz Garcia offered some insight into the diet that has helped her maintain her exquisite supermodel physique.

Breakfast might include tea without milk, a small fruit bowl and three organic egg whites served with green peppers, spinach, spring onions and parsley.

She could then have a lunch of 170g of turkey over 170g of quinoa or 90g of basmati rice, paired with stir-fried vegetables, the nutritionist told Women's Health.

Dinner could be 170g of salmon with garlic and lemon, with a side of mixed greens salad with cucumber and broccoli florets and a tablespoon of olive oil as dressing.

Heidi was also able to indulge in desserts, which would be either dark chocolate that was 70% cocoa, or yogurt or a fresh sorbet. 

As far as exercise was concerned, she confessed that her 'really great' treadmill 'just sits there unused' because she did not 'have time to use it.'

However was able to integrate physical activity into her daily routine, such as bicycle rides with her children and walks with her dogs.
