Heidi Klum, 50, goes TOPLESS on a beach in St Barts where she passionately kisses her steamy husband Tom Kaulitz, 34

Heidi Klum took full advantage of the warmth of St Barts as she escaped the wintertime chill for a Caribbean Christmas.

The 50-year-old fashionista, who spent her Yuletide on the French island, is still enjoying her luxuriously sun-drenched holiday there.

And one day before New Year’s Eve, the smoldering sensation put her supermodel credentials on display as she frolicked topless across the beach.

She wore a barely-there set of bikini bottoms that hinted at her pert derriere as she strutted her stuff across the sand that day.

During her latest day on the water, Heidi was also spotted passionately kissing her husband Tom Kaulitz, 34, who is part of the German rock band Tokio Hotel.

Her flesh-flashing public appearance allowed the Teutonic blonde to showcase her enviably taut midriff and her vertiginous legs.

Shielding her face from the rays with a baseball cap and a large pair of shades, she let her dripping-wet locks tumble freely over her shoulders.

Heidi, whose native Germany boasts several nude beaches, ornamented her look with jewelry including bracelets and a long pearl pendant.

In a tip of the hat to the festive season, Heidi headed into the water in an inflatable donut that came with a large pair of antlers.

Tom joined her, floating in the shallows beside her and snapping a few photos that in due course wound up on her Instagram page.

Eventually the pair became overwhelmed with affection for each other and Heidi leaned over the edge of her donut to plant a kiss on Tom.

The two of them could also be laying close together on the sand with the steamy Caribbean sunshine beating down on them. 

Heidi also took to her Instagram with some loved-up clips from the sunny day, including one of Tom kissing her, and another one of her enjoying her topless swim.

‘Love spending time with you ❤️’ she captioned the post.

A few months ago, Heidi furnished her fans with a tantalizing insight into her envy-inducing figure, revealing on her Insta Stories that she weighs about 138 lbs.

Heidi posted a video of her stepping on a digital scale, where the number on the screen fluctuated between 137 and 139lbs.

She also shed some light on the diet that has helped her retain her svelte frame, dishing that she eats a low-fat breakfast of poached eggs in a warm chicken broth.

Earlier this year, she told Red Online she once had to exert discipline over her diet as a model, but that she has now gotten ‘so used to it.’

The blonde bombshell explained: ‘There are so many choices, just pick the right things. Because then you don’t have the struggle.’ 

A few years ago she told Entertainment Tonight: ‘I don’t really have a specific diet. I just eat very healthily. You know, I start with great smoothies in the morning.

She spilled: ‘I also have four children so we cook a lot. I don’t really eat out a lot. I think when you eat out a lot or order food in a lot, then it kind of gets a little tricky, because you don’t know what people are putting in there, so I cook a lot.’

Said she: ‘I do three big meals, but really my last one is at 6pm. I eat with my kids. I think that also helps a little bit. I think when you eat a little on the earlier side, it has time to digest and I think it is a little bit better for your body.’

Tom is Heidi’s third husband, having tied the knot with her in 2019, five years after she finalized her divorce from her previous husband Seal.

Heidi and Seal were married from 2005 until 2014 and they welcomed three children together biologically – Henry, 18, Johan, 17, and Lou, 14. 

Meanwhile Heidi’s daughter Leni, 19, resulted from her previous relationship with Italian businessman Flavio Briatore, but in 2009 Seal legally adopted her as well. 

In recent years Leni has followed her mother’s footsteps into the modeling business, prompting persistent allegations of being a ‘nepo baby.’ 

Over the past year Heidi has been deluged with backlash more than once for posing with Leni in lingerie shoots for Intimissimi.
