The French model, famously labelled the most beautiful girl in the world by Vogue Enfants after entering the fashion industry as a child, was in attendance as Australian brand Zimmermann . 

The previous day, Blondeau confirmed her engagement to Attal in a series of social media posts after the DJ proposed with a £34,000 ring during their spring break at the five-star Four Seasons Astir Palace Hotel in . 

Wearing a cropped leather jacket and sweeping white lace skirt, the model, 24, claimed the spotlight as she took her seat on the front row alongside actresses Alice Isaaz, ,  and . 

Celebrity jeweller and gemologist Benjamin Khordipour, of based Estate Diamond Jewelry, has described her engagement ring as 'approximately two carats, cut in an oval shape with an excellent cut quality.'

He told the Daily Mail: 'Based on the photos, I would estimate the diamond to be around E color and VVS1 clarity. The design is very modern and minimalist, featuring a simple 18K yellow gold four-prong setting.

'The elegance of the ring comes from its simplicity, which draws the viewer’s attention entirely to the center diamond.

'I estimate the value of the ring to be around $45,000 (£34,000).'

He added: 'Over the past few years, I’ve noticed many celebrities gravitating toward oval-shaped solitaire engagement rings.

'Interestingly, this minimalist style echoes the late 1800s, when solitaire engagement rings were especially fashionable and prized for showcasing the beauty of a single diamond.'

The engagement, a surprise to Blondeau's six million plus social media followers, comes almost six years after the enigmatic model embarked on a relationship with Attal, whose own Instagram account remains refreshingly private.

While their relationship has mostly been conducted away from the public eye - Attal rarely features on Blondeau's social media platforms - the couple have been seen enjoying romantic holidays together in Saint Tropez.

The model was previously involved in brief relationships with YouTuber Raphaël Le Friant, and French DJ, Milane Meritte. She and Meritte first went Instagram official in January 2019 and would regularly be spotted on dates in Los Angeles prior to their split.

Blondeau was three years old when she was catapulted into the spotlight after an agent for the legendary fashion designer Jean Paul Gaultier picked her out of a crowd in The Champs-Elysees and .

The model daughter of retired footballer Patrick Blondeau, she walked for Jean Paul Gaultier at the age of four and then later, aged 10, became the youngest ever model to .

She would famously be named the 'most beautiful girl in the world' by Vogue Enfants, an accolade she won on two separate occasions.

But the editorial attracted criticism at the time, for being too 'sexualised' as Blondeau wore short dresses and makeup.

Her fashion designer mother Veronika Loubry later defended the cover, telling one French newspaper: 'The only thing that shocks me about the photo is the necklace that she's wearing, which is worth three million Euros, or about $4.3 million.'

Six years later, she made her adult runway debut in February 2017, when she walked for Dolce & Gabbana at Milan Fashion Week. The debut was such a success the designer duo invited her back to walk for them again in September 2017.

Blondeau was also chosen as a brand ambassador for L'Oréal, and named the face of a perfume by French designer Lolita Lempicka.

She shared screen space with Zendaya, Lucky Blue Smith, and Presley Gerber, when Blondeau was chosen to be a part of Dolce & Gabbana's Spring 2017 campaign.

Blondeau's parents were married from 2002 to 2016 before their divorce, with her mother eventually moving on with a new partner - producer Gérard Kadoche.

As well as her infamous cover shoot for Vogue Enfants, Blondeau has worked for some of the biggest couture brands in the world including Miu Miu, Dolce & Gabbana, L'Oréal Paris, Versace, Ralph Lauren and Hugo Boss.

In a 2018 interview with The Telegraph, she said she distanced herself from the girl who was once declared the world's 'most beautiful'.

She said: 'Even today, people are like, "you are the most beautiful girl," and I'm like, "no, I'm still not, I'm just a human being, a teenager."'
