Heidi Klum proves she still looks youthful on her 53rd birthday as she stars in a new bikini campaign

German supermodel Heidi Klum turned 53 years old on Monday, the same day that Marilyn Monroe and Amy Schumer have birthdays.

And the size four star proved with a new Calzedonia bikini ad campaign for summer 2026 that she is still in excellent shape.

The 5ft9in runway veteran was seen in various skimpy string swimsuits as she posed on the beach in Malibu.

In the campaign, Klum presented 'a curated selection of key pieces that highlight the diversity of Calzedonia's current collection,' a statement from the brand shared.

Klum continues to model and is also still thriving in the TV world as she has returned to Project Runway for its 21st and 22nd seasons.

The new Calzedonia campaign is eye popping.

Art directed by Thomas Hayo and photographed by the Morelli Brothers, the images transport fans to the California coast.

'The setting perfectly reflects the inspiration behind the campaign: California's carefree and positive lifestyle,' the brand said in a statement.

'Between poolside moments and endless skies, Klum appeared effortlessly confident, natural and glamorous.'

This comes weeks after Klum said she was thrilled by her cameo in The Devil Wears Prada 2.

The part-time actress has a small part in the long-awaited sequel to the 2006 original film that survived the final edit.

Klum - who stars in a scene alongside Emily Blunt - told People: 'I was in the first Devil Wears Prada movie ... I mean, literally just the smallest little cameo. I was asked to come back again for The Devil Wears Prada 2 and was so excited because they didn't cut me out.

'Sometimes you do these things and then you go and watch this and you're like, "Where the heck am I? I wasn't even in it." So I was super excited that I made the cut, even though it's super short, I have my scene with Emily Blunt.'

The former Victoria's Secret Angel feels fortunate that she's appeared in so many high-profile films and TV shows.

She said: 'Over the years, I've been so lucky that I got to be in some of the most iconic TV shows or movies where I had small cameos.

'I was kind of going down memory lane ... I mean, I did Desperate Housewives with Eva Longoria, I did Spin City with Michael J. Fox — [that was] six episodes — I did How I Met Your Mother, Sex and the City walking over Sarah Jessica Parker, Oceans Eight with Sandra Bullock... I was so lucky that I got to be in some of the most iconic TV shows and movies over the years.'

The mother of four admitted that she's 'not an actress' - but she relishes the challenge of leaving her comfort zone.

The model describes herself as a 'curious' person and she's willing to give anything 'a shot'.

She said: 'I think it's always important for anyone to be curious, to have goals, interests, and it's always been like that for me.

'I always dabbled into different things because of the interests that I've had and also doing things that are not on my bingo card, let's say, or that are not something that I've learned to do like modelling.

'I'm not an actress, but I got to dabble into so many different fun things. And it's because I'm curious and I want to just give it a shot. And I'm always like, 'Why not?'' 

These images have been released on the 11-year anniversary of Donald Trump calling the German wonder 'no longer a 10.'

The statement made headlines all over the world and Klum even responded.

The Vogue cover girl posted a humorous video on Twitter where a man in a Trump mask tore a 10 sign off her shirt, revealing a 9.99 tag. 

She used a hashtag for Heidi Trumps Trump. She later gave a very classy response: 'In my book, every woman is a 10.'
