Heidi Klum looked incredible as she modelled an array of bikinis and rang in her 52nd birthday on Monday.

The German supermodel, who is working with Calzedonia for the launch of its summer collection, showed off her figure in a selection of satin swimwear.

Heidi posed by the pool in a rust coloured triangle set, that featured tie side bottoms, before changing.

In another stunning snap, she slipped into a powder blue bikini and laid on her side against the skyline.

The new photoshoot dropped on the model’s 52nd birthday, which she celebrated with her close friends and family.

In an update to her Instagram Story, Heidi wore a figure-hugging mesh dress with a pair of quirky sunglasses while enjoying dinner outside.

She posed for a loved-up photo with her husband Tom Kaulitz, before joining Sofia Vergara for a glass of wine.

The new photoshoot comes after her model daughter Leni, 20, hit back at trolls who criticized their joint risqué lingerie ads in her cover story with Glamour Germany.

The mother-daughter duo made headlines last year when they appeared in a sexy ad for Italian lingerie brand Intimissimi.

But Leni said she is blocking out the haters and focusing on her career and life in New York City.

She told Glamour: ‘I always try to remember that no matter what you do, there will always be someone who doesn’t like it.

‘You simply have no control over it and you can’t focus too much on the negative. That can easily happen, especially if you spend a lot of time on social media. But there are so many more positive reactions.

‘Oh, and: Most of the comments are in German, and I don’t really understand many of them. That helps too, of course!’

Heidi shares her oldest, Leni, with the Italian businessman Flavio Briatore, whom she split from while still pregnant.

She began a relationship with the singer Seal shortly afterward, and the two tied the knot in 2005, four years before he adopted Leni at the age of five.

Heidi and the singer went on to share three biological children: sons Henry, 19, and Johan, 17, as well as daughter Lou, 15.

She wed Tokio Hotel guitarist Tom Kaulitz in December 2018.

Last October fans were vocal about how disturbing they found the photos of both Heidi and Leni showing off their bodies in lingerie while arm in arm.

Commenters on Intimissimi’s Instagram post were largely positive, but several vocal users were concerned or disturbed by the mother–daughter display.

‘Dude that’s your mom,’ one person put it bluntly.

Another person wondered, ‘Which normal mom would pose together with her daughter in lingerie?’

‘You simply have no control over it and you can’t focus too much on the negative. That can easily happen, especially if you spend a lot of time on social media,’ Leni told Glamour

‘Family business it must be continued!’ replied one user.

‘What normal mom would pose together with her daughter in lingerie?’ one concerned fan shared on social media.

‘There’s something wrong there,’ added another person in agreement.

Heidi blocked comments on her post.

In her photos and video, Heidi showcased her toned abs in a lacy burgundy set as she posed next to Leni, who had on a black bra and panties.
