Newlywed Adam Levine and his Maroon 5 bandmates are real-life wedding crashers in their new music video for "Sugar," but how did they pull it off?

The band walks into a series of venues, seemingly unnoticed, and sets up their performance equipment behind a curtain on stage. The curtain drops, and we see a shocked bride and groom attempting to process the fact that MAROON 5 IS PLAYING AT THEIR WEDDING!!!

The feel-good clip hit the web on Wednesday after a series of teasers on social media from the band, but now fans are wondering whether the couples were truly surprised or simply exercising their best versions of Taylor Swift's now-retired surprise face.

ET asked the band just that.

"Only the grooms knew in each case," a rep for Maroon 5 tells ET. "However they disclosed it to their bride and the wedding party, we're not sure, but they all wanted it to be as equally a surprise as we did. They had stages set up for their actual wedding band already. All we did was some simple continuity changes to match each one as best we could."

The rep also notes that certain shots (like Levine's solo performance) "had to be shot separately from the real weddings due to time and space constraints that were given."

The video, directed by Wedding Crashers helmer David Dobkin, was filmed over a full three-day weekend in Los Angeles at venues from Glendale to Marina del Rey and everywhere in between, with the band putting in 10-12 hours of work and travel each day.

"It was really stressful to arrange all of it, but it was super fun," Levine told ET's Kevin Frazier on the Golden Globes red carpet. "It felt good to kind of, you know, surprise these people and make them happy. [We were] happy that they liked our band, too – [that] would have been a total disaster."
