This glamazon made a very rare appearance at a swanky event on Monday evening.

The beauty is tall and fashion looks good on her, which means she could turn into a model. And she has the background for it.

Her father is a luxury goods executive who is worth a fortune.

And this blonde's stepmother is a massive movie star who has worked with George Clooney and Angelina Jolie.

She is also big on Instagram and often shows up at fashion events to support her husband.

Do you know who this buddy star is?

She is 22-year-old Mathilde Pinault.

Her stepmother is Salma Hayek and her dad is François-Henri Pinault, 61. Her mother is Dorothée Lepère.

Salma worked with Clooney on From Dusk Till Dawn and with Jolie on The Eternals. 

Pinault is the CEO of Kering, a luxury goods company that owns brands like Gucci, Balenciaga, Bottega Veneta, and Yves Saint Laurent.

Mathilde has two siblings: brothers, François (whose mother is Dorothée Lepère, a home decor specialist) and Augustin (whose mother is supermodel Linda Evangelista).

And her her half sister is Salma's daughter Valentina.

Mathilde was with Salma and François-Henri on Monday when they attended a Gucci event.

It was the Gucci Cruise 2025 Fashion Show at Tate Modern in London. 

The looker wore a black corset top that showed off her arms and tummy. She added black jeans and pointy black heels. Her accessories were a Gucci belt and purse.

Her blonde hair was worn down over her shoulders. 

Last year the Frida actress brought her daughter Valentina and stepson Augustin to the TIME 100 Gala, which took place at Jazz at Lincoln Center in New York City.

Salma has been wed to François-Henri since 2009.

Augustin is the son of Linda and François-Henri who were in a romance from 2005 until 2006. 

Salma has posted images with Augustin to social media in the past, but is not often seen with him in public. 

Pinault is a French businessman, the chairman and CEO of Kering since 2005, and president of Groupe Artémis since 2003. 

Under his leadership, the retail conglomerate PPR was transformed into the luxury fashion group Kering. 

He oversees luxury brands like Balenciaga, Bottega Veneta, Gucci, Alexander McQueen and Yves Saint Laurent.

Linda was in the news last year for her claims CoolSculpting — a FDA-cleared 'fat-freezing' procedure — left her 'disfigured.'

Evangelista filed a lawsuit in September suing CoolSculpting's parent company, Zeltiq Aesthetics Inc., for $50 million in damages.
