The creative director and Colin Firth parted ways in 2019 after 22 years of marriage.
And on Thursday, Livia Giuggioli exuded elegance in a strapless peplum gown as she posed with Cate Blanchett, both 53, at the Green Carpet Fashion Awards in Hollywood.
The Italian beauty looked sensational in the floor-length number, which boasted intricate gold detailing, as she hosted some of her famous friends at the event.
Posing upon arrival at NeueHouse, actress Cate commanded attention in a mint green trouser suit, styled with an eye-catching baby pink bow at her waist.
Livia was also joined by designer Tom Ford, 61, climate activists Sophia Kianni, 21, and Nalleli Cobo, 21, at the awards which celebrate positive forces in fashion and entertainment and their collective ability to move culture forward.

Last month, removal men were spotted outside Livia’s home in south-west London loading up a van with furniture, while work – which could cost up to £2million – is being carried out on the house in her name.
Colin first moved out in 2015 when the couple split before reuniting, splashing out £1.6million on a luxury three-bedroom flat nearby.
The couple met on the 1996 BBC drama Nostromo before tying the knot in Tuscany, Italy a year later.
They have sons aged 21 and 19 while Colin also shares a son, actor Will, 32, with former partner Meg Tilly, his co-star in the film Valmont.
Back in November 2019, Colin announced he had split from his wife Livia but said they remained ‘united in their love for their children’ almost two years after it emerged she had an affair with her childhood friend.
A statement from their publicists said: ‘Colin and Livia Firth have separated. They maintain a close friendship and remain united in their love for their children. They kindly ask for privacy. There will be no further comment’.
Their split came after it was revealed 18 months earlier that Livia was alleged to have had a year-long affair with Italian journalist Marco Brancaccia.
She sparked a police investigation after claiming her childhood friend Marco harassed her with a ‘frightening’ barrage of messages.

The Oscar-winner – who maintained a dignified silence over the affair – confronted his wife over a ‘heartbreaking and malicious’ email from her ex-lover in March 2018, which contained revelations ‘designed to wound’ the King’s Speech star.
At the time, a friend of Colin’s said: ‘This guy Marco basically told Colin everything he had been doing with his wife for a year. The email was a detailed diatribe, humiliated Colin and was designed with no other motive than to wound.
‘He described intimate meetings that would devastate any husband – no matter what the state of their marriage. And he did so with the misguided and hopeless belief he could destabilise the efforts being made by Colin and Livia to sort things out.
‘Colin presented this to his wife and in what must have been a very difficult confrontation. But he is the man that he is and has maintained his dignity throughout.’
As well as the email to Colin, his wife claims she received phone calls, lived in terror and believed she was being followed, and said emails containing pictures of her were sent to her husband after the pair reunited.
But Marco, told The Times that Livia had invented the claims to cover up their affair, which happened between 2015 and 2016.
A spokesman for the couple at the time said: ‘A few years ago Colin and Livia privately made the decision to separate. During that time Livia briefly became involved with former friend Mr Brancaccia. The Firths have since reunited.
‘Subsequently, Mr Brancaccia carried out a frightening campaign of harassment over several months, much of which is documented. For obvious reasons, the Firths have never had any desire to make this matter public.’

In 2017 it emerged that Colin had followed in the footsteps of his children and applied for dual UK and Italian citizenship, while Livia was applying for a British passport.
Livia is an environmental activist and co-founder and creative director of Eco-Age, a sustainable consultancy firm.
She is also a founding member of singer Annie Lennox’s women’s advocacy group The Circle, and has won the UN Leader of Change Award and the Rainforest Alliance Award for Outstanding Achievement in sustainability.
Acclaimed actor Colin is best known for playing a number of famously stiff-upper-lipped English figures on the big screen, including Bridget Jones’s Mark Darcy, Love Actually’s Jamie, and King George VI in The King’s Speech.
