Heidi Klum looked sensational as she took to the catwalk for the Magnum ice cream fashion show during the Cannes Film Festival on Thursday.

The German supermodel, 52, was joined by her her nepo baby son Henry Samuel, 20, who also hit the runway during the fashion event.

Heidi wowed in a strapless lime green dress which showcased her incredible figure and ample cleavage as she walked down the runway with fashion stylist Law Roach.

The mother and son were seen supporting each other backstage before the show began, as they revelled in the limelight together on the night.

Henry, whose father is Seal, has recently pursued a modeling career and made his runway debut at the Lena Erziak Haute Couture show, last year.

He also hit the catwalk as he modelled a sheer top and multi-layered coat as he tucked into an ice cream.

Heidi was earlier seen leaving the Hotel Martinez in shiny strappy heels and sunglasses.

Heidi has been posing up a storm at the festival so far after she wowed on the carpet in a strapless peach gown from the Elie Saab brand on Tuesday.

She later changed into a low-cut gold fringed dress as she attended the star-studded opening ceremony dinner alongside Demi Moore and Ruth Negga.

While Heidi is known for her glamorous appearances, earlier this month she shocked fans after she arrived at the Met Gala looking unrecognisable.

With this year’s theme, Costume Art, and the dress code, Fashion is Art, leaving plenty of room for interpretation, Heidi leaned all the way in, arriving in a look that could only be described as a living statue.

Wrapped in sculptural, stone-like detailing, she appeared to channel both the Statue of Liberty and a classical Greek figure in her striking ensemble.

The dramatic transformation immediately drew comparisons to the elaborate costumes from her famously over-the-top Halloween parties.

One of the biggest stunts was made by Heidi Klum who covered her entire face with prosthetics to look like a stone statue.

And fans were quick to react on social media, with one follower commenting: ‘Heidi Klum found a second Halloween in the Met Gala’.

Others wrote: ‘She is on theme and she can repeat this for her Halloween party’; ‘I love how she brings Halloween spirit to everything.’

But not everyone was impressed, with one critic tweeting: ‘This is genuinely disturbing.’

Another simply said: ‘I can’t move on from this.’

When being interviewed by Ashley Graham she said that she was not that uncomfortable because the dress moved easily.

Heidi and Law Roach received plenty of applause on the runway

Elsewhere Hollywood icons Dame Joan Collins and Jane Fonda brought the glamour to the red carpet at the 79th Cannes Film Festival’s opening ceremony at Palais des Festivals on Tuesday night.

Joan, 92, looked sensational in a white gown which she teamed with a diamond necklace and black gloves.

The Dynasty actress was joined by her devoted husband Percy Gibson, 61, on the carpet.

Jane, 88, who boasts an impressive six-decade career, was age-defying as she dazzled in a floor length black sequin dress.

The leading ladies created a buzz as they posed for photographs thanks to their A-list status, which comes after years of models dominating the red carpet.
