The Oscar-winning actor made a rare public appearance alongside girlfriend Eleonora Perboni at the London premiere of Disclosure Day on June 4.

The couple opted for matching looks for the outing with Colin, 64, wearing a black suit, white dress shirt and black tie. Eleonora also donned a black suit, pairing it with a sparkly black clutch and strappy heels. 

Colin and Eleonora have done their best to keep their relationship out of the spotlight, with the Disclosure Day appearance marking the pair’s second public outing. After all, the two first hit the red carpet together at a 2025 BFI London Film Festival screening of Hamnet in October.

While neither Colin nor Eleonora have confirmed when their romance began, their latest outing comes almost seven years after Colin and his ex Livia Giuggioli announced they were divorcing in 2019 after 22 years of marriage.

"Colin and Livia Firth have separated," their reps told E! News in a joint statement at the time. "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."

The former couple—who share sons Luca, 25, and Matteo, 22—finalized their divorce in 2021. 

Prior to their split, Livia admitted to having an affair with Marco Brancaccia while she and Colin were temporarily separated between 2015 and 2016.

Despite their divorce, Colin and Livia have been able to maintain a friendship, with the Pride & Prejudice actor even becoming close to her husband Callum Grieve.

"Colin and Callum are good friends and they're both huge Arsenal supporters," Livia told HELLO! magazine in 2025. "Arsenal is a big theme in our family."

The 56-year-old added that she and Colin—who also shares son Will, 35, with ex Meg Tilly—are “always together.”

"Colin and I have a wonderful relationship," Livia said. "We have worked on that a lot, and in keeping the family together. I have a partner; he has a partner and we’re all together all the time. It's an extended, crazy family."
