Paris Fashion Week is now well underway - but there was one familiar face that fashion fans weren't expecting to see.

The Haute Couture event, which runs from July 6 to July 9, has already been flooded with a whole host of A-listers from Jennifer Lopez to Cardi B.

But another big name to hit the French capital for the occasion was Kimberly Guilfoyle.

Guilfoyle, 57, appeared at the Haute Couture Fall/Winter 2026/2027 showcase for Greek designer Celia Kritharioti on Thursday in her capacity as US Ambassador to Greece.

The former cable news host dazzled in a sheer high-neck maxi dress that was adorned with hundreds of jewels to protect her modesty.

She accessorized with a pair of cream peep-toe platform heels and what appeared to be a Crocodile Himalayan Lady Dior Mini by Christian Dior, which are worth thousands of dollars.

Guilfoyle wore her long brunette tresses in loose curls swept in front of her shoulders and opted for her signature smokey eye makeup before adding a pop of color with bold red nail varnish. 

She was spotted posing for a series of photos before taking her seat alongside fashion icon Fancy James. 

Guilfoyle shared an Instagram post by the Attica Times that celebrated her appearance at the event.

Alongside a series of pictures and video, it read: 'Kimberly Guilfoyle stole the spotlight at Celia Kritharioti's spectacular fashion show in Paris.

'A glamorous evening celebrating Greek haute couture on the international stage. Elegance, style, and timeless sophistication.'

Many of her two million followers were stunned that she was there - but also offered words of support.

'Looking absolutely fabulous,' one wrote.

'You look so beautiful,' another shared, as a third simply added: 'The most beautiful woman in the world.'

Guilfoyle has been the US Ambassador to Greece since November 2025.

Her unexpected appearance comes shortly after her ex Don Jr tied the knot with Bettina Anderson.

Guilfoyle had been dating President Donald Trump's eldest son since 2018. The pair got engaged on December 31, 2020 but it was not made public until January 2022. 

However, she was reportedly 'blindsided' when images emerged in 2024 of her fiancé dining with Bettina.

Bettina recently became the newest member of the Trump family after she and Don Jr legally tied the knot in a Palm Beach ceremony in May.

A few days later, they followed it up with a sun–soaked event limited to their closest friends and family members.

More than 40 of their loved ones attended their luxurious Little Pipe Cay celebration, which included top-secret preparations and planning to keep the event as private as possible on the isolated paradise island.

It is not known how much the event cost, but renting the main 11–bedroom house on 38–acre Little Pipe Cay is a jaw-dropping $750,000-a-week in high season.
