Third wheeling.

Ben Affleck was seen tagging along during Matt Damon and his wife Luciana Barroso’s dinner date on Saturday.

The trio was spotted engaging in conversation after they departed the Beverly Hills, Calif., steakhouse Steak 48.

The “Gone Girl” actor smiled and hugged both Damon, 54, and his wife, 48, before he took off.

For the outing, Affleck, 52, rocked a black leather jacket over a black T-shirt and blue jeans.

His “Good Will Hunting” co-star sported a white, short-sleeved button-up shirt, khakis and white sneakers, while Barroso stunned in a chic tan pantsuit.

Their dinner date came hours after the actors attended Netflix Tudum 2025 to tease their forthcoming crime film, “The Rip.”

During the live event, Affleck joked about his BFF’s gray beard, which he has been sporting on the set of Christopher Nolan’s upcoming movie, “The Odyssey.”

“I trusted Matt would shave the beard before Tudum — and here we are,” he quipped to the audience.

According to Netflix, the film follows a team of Miami cops who discover millions of dollars in cash inside a neglected stash house.

“Things start unraveling the moment they find the money,” Affleck added onstage. “It’s less about what they’ve found and more about what it brings out in them.”

Damon and the “Accountant” actor have been best friends since their childhood years and have collaborated in several projects, including “Air” and “The Last Duel.”

Last November, Page Six exclusively reported that Affleck’s divorce from Jennifer Lopez was impacting production on “The Rip.”

“With Ben’s divorce and everything going on in his personal life, production on the film has slowed and there’s no release date at the moment,” a source told us.

“They’re still working on the project, but there’s not a firm deadline with any of it.”
