When a fan called a sweet (and slightly odd) moment between Dave Franco and his wife Alison Brie “diabolical,” Franco was quick to clarify—it’s not their usual routine. He shared the details exclusively with TooFab recently.

Turns out, Franco does have a line when it comes to his relationship with Brie. The topic came up while he walked the red carpet for his upcoming movie Regretting You—a chat that followed the pair’s experience filming Together, where they spent most of the time practically glued to each other.

A TikTok video of the couple talking about their 2011 “meet cute” at New Orleans’ Mardi Gras went viral not long ago, and it’s full of relationship vibes. In the clip, they talk over each other, gaze at each other affectionately, and then—out of nowhere—Brie takes the gum from her mouth and hands it to Franco.

“I feel okay talking about it now, since we’re done with that press tour,” Franco told TooFab. “That was for Together—that movie’s total chaos. We thought, ‘Let’s lean into the chaos. Let’s do weird stuff for this press run.’”

Fans couldn’t stop weighing in in the comments. One person called the gum moment “a whole other level of love,” while another labeled it “diabolical.” But Franco was clear: “That’s definitely not our usual vibe,” he said firmly.

So where does Franco draw the line with Brie? It’s simple—sharing toothbrushes.

“That’s a hard no—we don’t even talk about it,” he emphasized to TooFab. “If you bring that up? I’ll judge you.”

He also joked that the gum moment was nothing compared to their on-screen antics: “That’s the tamest thing we did in Together,” he added, referencing the film.

Later, the conversation shifted to Regretting You and the idea of regret—so TooFab asked Franco if he’d ever regretted a Halloween costume.

“Honestly? I’m not big on dressing up for Halloween,” he admitted. “I’m trying to think of what I’ve worn… Just good, simple costumes. There was a full duck onesie—total classic. That one was actually great!”
