Just because they're having a high-profile romance, doesn't mean Riverdale's Cole Sprouse and Lili Reinhart can't have a low-key date night...

A source tells E! News that the sweethearts, who play onscreen loves on the hit CW show, took in a movie in Vancouver, Canada on Friday while taking a break from filming.

"Lili and Cole sat beside each other. There was no PDA but they did whisper to each other and laughed during the movie—they were in a happy mood,” an eyewitness tells E! News.

The insider says that the lovebirds brought along with mom Amy Reinhart and one of her two sisters to see the flick. The foursome took in the 7:25 p.m. showing of Baby Driver at the Scotiabank Theatre on July 28.

But what about the really important info, like what kind of snacks did the stars sink their teeth into? Turns out that Sprouse was munching on MiniMelts during the Ansel Elgort-helmed movie.

The eyewitness added, "After the movie they rushed outside because it was getting chaotic. They were getting recognized."

However, Sprouse, who plays Jughead on the Archie-inspired show, stopped to take a photo with a lucky fan, but asked that she do it quietly. 

A rep for Reinhart, who plays Betty, declined to comment.

The co-stars are currently in the land of the Canucks while filming the second season of their drama. 

Last week, E! News reported that TV's "Bughead" were dating in real life, after the twosome were spotted canoodling at EW's 2017 Comic-Con party the weekend prior. Multiple eyewitnesses confirmed that the actors "could not keep their hands off of one another" during 2017 Comic-Con weekend.

Neither Reinhart, 20, nor Sprouse, 24, has publicly commented on their budding romance. However, the former Suite Life of Zack and Cody star told MTV News he and Reinhart were "strictly in the friend zone."

The actors were first romantically linked after Sprouse photographed his co-star in a field. "Lili and I play characters who are dating," he told MTV News, "so just about any time she and I go out into the wilderness, it's, 'Oh, my god!' Truthfully, I'm a sucker for friends, fashion and framing."

Whatever you say, Juggy...
