Ben Affleck reacts to ‘sad Affleck’ Grammys meme in new Dunkin’ commercial

Meet B.Lo.

With a heroic sense of humor, actor Ben Affleck poked fun at his unimpressed look at last year’s Grammy Awards … in a new commercial for Dunkin’ Donuts.

In 2023, when wife Jennifer Lopez clarified that his mug of misery that became a social-media meme was actually Affleck’s “happy face,” fans joked online that the “Gone Girl” star looked like he’d rather be at Dunkin’.

So, the donut chain seized the opportunity.

The spot that debuted during Sunday’s Grammy Awards starts with Affleck, 51, watching a cable news broadcast of himself and Lopez, 54, at the 2023 Grammys, with a header that reads, “The Boredest Man in the World.”

“He’s bored?,” Affleck broodingly says back to the TV. “No, studying. Always watching. I could do that. How hard can it be?”

By “it,” we learn, he means a music career.

Affleck phones somebody and says he had a dream.

“I had come up with some beats and then you were like, ‘Maybe you should put that on a record,’ ” the actor says. “I even had like a persona, like J.Lo or like B.Lo.”

As if in a “Rocky” montage, we then see Affleck wooing a music producer, working in the recording studio and stumbling through TikTok. 

Then — here’s where the coffee chain comes in — he dons a gold chain with a frosted donut on it. 

“They tell you you’re no good,” he says dramatically. “You’re a goofy, middle-aged, clumsy white guy with no rhythm and you can’t sing on key. You’re not coordinated. That means I can’t be a pop star? Underestimate Boston at your peril.”

Cambridge, Massachusetts-raised Affleck has teamed with the Massachusetts company several times before.

This latest collaboration, with TikTok star Charli D’Amelio, comes just over a week before the release of his new film starring Lopez, “This Is Me… Now: A Love Story,” in theaters Feb. 16.
