A source previously told PEOPLE that Pitt had a “low key” week planned alongside his girlfriend, who was also celebrating her birthday

Brad Pitt turned 60 with a bang!

The actor and his girlfriend Ines de Ramon were photographed Tuesday evening at a party held in his honor at Mother Wolf in Los Angeles, with close friends in attendance, a source tells PEOPLE.

Pitt and de Ramon’s birthdays are just a day apart: Pitt’s was on Monday, while de Ramon rang in her 34th on Tuesday.

The Oscar winner was photographed outside the restaurant in black slacks and a black button-up with an eclectic gold print.

Carrying a yellow balloon, his girlfriend was outfitted in a cream-colored dress, coordinating with a long matching scarf and black tights.

Attendees were spotted holding various pieces of artwork while leaving the celebration — one guest was seen carrying a large photo of Pitt and de Ramon making funny faces at the camera. Pitt, who is also an artist, was photographed holding a piece of artwork featuring two wolves.

PEOPLE learned on Pitt’s birthday Monday that the actor would be celebrating with a “low key” week, which would include laid-back plans with his jewelry-designer girlfriend and friends.

Pitt and de Ramon had their first public outing together in November 2022, when they were photographed at a Bono concert in L.A. At the time, sources told PEOPLE they’d been dating for “a few months.”

Last month, an insider told PEOPLE that the year-long romance “is Brad’s first proper relationship since [his] divorce” from Angelina Jolie.

“He introduces [Ines] as his girlfriend,” continued the source, who also said Pitt “is doing great with” de Ramon.

“It’s great to see him in a good place. Ines makes him very happy,” the insider added.

Pitt is currently enjoying some downtime before going back to work on his Formula 1 movie. PEOPLE reported on Monday that he will resume filming at race tracks including the Daytona International Speedway in the new year.

The actor has a strong film slate next year, which will also see him reunite with George Clooney on the AppleTV+ film Wolfs, directed by Spider-Man: Homecoming’s Jon Watts. It was recently announced that Sony Pictures will release Wolfs in theaters prior to its streaming debut, likely in 2024.

Joking about their onscreen reunion in a recent interview with Entertainment Tonight surrounding his new film The Boys in the Boat, Clooney, 62, said of his fellow Oscar winner, “Pretty boy Pitt? Yeah, he needed work. He’s an up-and-comer.”
