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 colleague in “Good Will Hunting” opted for a white short-sleeved button-up shirt, khaki pants, and white sneakers. On the other hand, Barroso looked stunning in a stylish 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 playfully commented on his best friend’s growing gray beard, a look he has been rocking for 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.

On stage, Affleck teased, “Once they discover the money, things start to spiral out of control. It’s not so much about what they’ve found, but rather about how it changes 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.”
