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 was seen wearing a white, short-sleeved button-up shirt, khakis, and white sneakers, while Barroso dazzled in an elegant 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 jokingly remarked on his best friend’s gray beard, which he has been growing for his role in Christopher Nolan’s upcoming film, “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 falling apart the moment they discover the money,” Affleck mentioned onstage. “It’s not just about what they’ve found, but more about what it reveals 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.”
