Heidi Klum showed off her impressive bikini body in a new racy snap shared to Instagram on Monday.

The supermodel, 49, displayed her stunning physique while soaking up the sun in her garden.

Turning up the heat, Heidi went topless and donned a brown string thong in the selfie. 

Heidi wore her voluminous blonde locks down and let them flow freely in the wind and cascade past her shoulders. 

She sported a natural makeup look underneath a pair of stylish sunglasses, with a swipe of nude lipstick.

It comes after Heidi made waves at The Little Mermaid premiere on Monday evening. 

The model was a vision in a very sexy shimmering butterfly dress that left little to the imagination.

Posing up a storm at the Dolby Theatre on Monday, Heidi wore a winged, floral dress with tiny sheer skirt ad a flowing, translucent train.

The dazzling, silver wings and floral design expanded over her torso and displayed a hint of her svelte torso.

Her legs on full display, she accented her long limbs wearing tan heels.

Heidi’s hair was styled in loose, beachy waves with thick fringe skimming over her beautifully done-up complexion.

While Heidi is already naturally stunning, she took her features to the next level with smoky eye shadow and a dashing of radiant blush.

She also shared video of her getting ready for the premiere – in her bikini.

In video set to the Kali Uchis song Telepatia, Heidi laid out in her cherry print swimsuit as her glam team dolled her up.

She then frolicked around her backyard before changing into her stunning dress.

The upcoming, live-action remake of Disney’s classic The Little Mermaid stars Halle Bailey as Princess Ariel, Melissa McCarthy as Ursula, Jonah Hauer-King as Prince Eric, and Javier Bardem as King Triton.

In a cover story for Ebony , Halle revealed that playing Ariel, ‘…is all a part of God’s plan for me.’

Halle has been a star since she was a teenager. She’s also one half of the R&B singing group Chloe x Halle with her sister Chloe Bailey.

Landing the role of Ariel allowed her to spread her wings and explore her individuality.

‘It was the first thing I did by myself, independently,’ Halle revealed to the outlet. ‘I had to move across the world. Suddenly I was in London, and I was by myself. It really forced me to grow up.’

‘The whole filming experience was insane. It was the most intense, excruciatingly beautiful experience of my life. I mean, physically, mentally—all of the above,’ the actress admitted.

The Little Mermaid will be released in theatres on May 26.
