Brad Pitt, 60, and Ines de Ramon, 34, made their red carpet debut at the Venice Film Festival on Sunday.
The couple made a splash at the premiere of Wolfs where Pitt looked every bit the leading man in an oversized black suit.
But it was de Ramon who stole the spotlight in a stunning white one-shouldered gown, accessorised with gold earrings and a matching handbag.
The glamorous occasion marked the jewellery designer’s - who has been quietly dating Pitt for nearly two years -first official public appearance with the Hollywood star.
The cinematic event also saw George Clooney, 63, and his human rights lawyer wife Amal, 46, grace the red carpet in a vibrant yellow dress with delicate ruffles.
Long-time friends Pitt and Clooney were in high spirits as they celebrated the premiere of Wolfs.
In the film, the duo plays criminal clean-up specialists who unexpectedly find themselves hired for the same job—disposing of a body in a hotel room.
Pitt's relationship with de Ramon has largely flown under the radar, but their Venice appearance marked a major milestone.
The couple was first linked in November 2022 after being spotted together at a Bono concert, shortly after Ramon separated from her husband of three years, Paul Wesley. Their divorce was finalised earlier this summer.
Since then, Pitt and de Ramon have been inseparable. Pitt brought her to the premiere of his film Babylon in December 2022, and they spent his birthday and New Year's Eve together, even taking a romantic trip to Paris.
The couple was also seen together at the Santa Barbara International Film Festival in early February 2024, where they cosied up at the event as Pitt honoured his friend Bradley Cooper, according to Hello!
A source told People that the pair moved in together shortly after the festival, though de Ramon still maintains her own place.
“It's pretty recent. They're going very strong, and she's happier than ever,” the insider shared.
De Ramon was also spotted with the star at Silverstone in May, as Pitt continued to film his upcoming motorsports film F1.
It’s believed to be Pitt's first serious relationship since his split from Angelina Jolie, who filed for divorce in September 2016.
Jolie and Pitt met on the set of action comedy Mr & Mrs Smith and were married in 2014.
The actor has six children with the Lara Croft star, 49. The details of their divorce have yet to be finalised.
In May their daughter Shiloh Nouvel Jolie-Pitt became the first of their children to request a legal name change.
