Marriage ceremonies are often filled with surprises, but few are as shocking as having a world-famous musical group show up without a formal wedding invitation.

Grammy Award-winning musical group Maroon 5 set out to make a unique music video with an interesting premise; the band would drive around Los Angeles and "crash" weddings by giving the bride and groom an unexpected performance and filming their reactions along the way.
The music video eventually made its way to YouTube in January, where it has since been viewed almost 800 million times — placing it in the top 25 most-viewed YouTube videos of all time. 

The video serves as a type of wish-fulfillment for viewers. What bride or groom wouldn't want a wildly popular musical performance to make their wedding reception unique? Unfortunately, some Internet sleuths have deduced that the video, or at least parts of it, may have been staged. 

Madeleine Davies, Arts and Entertainment writer at The Muse, pointed out that one of the brides featured in the music video is "America's Next Top Model" contestant Raina Hein, who Davies claims is currently unmarried. More evidence arrived, like a Facebook post from actors Stephen and Barbara Woo claiming that they acted in the music video.

"Barbara and I are proud to have played the parents of the bride in this amazing Maroon 5 'Sugar' video," Stephen wrote on the pair's Facebook page, with screenshots from the music video in which he and his wife are visible. 

Maroon 5's representative told Entertainment Tonight that "Only the grooms knew in each case," but the rep admits that certain shots "had to be shot separately from the real weddings due to time and space constraints that were given."

Adam Levine, the lead singer of Maroon 5, also confirmed that some shots were staged, but affirmed that a majority of what is shown is genuine footage. 

"I do want to clear up something about the video," Levine told The National in June. “Half of the weddings we crashed and the other half were set up, we did that to cover our bases and to make sure we had all the footage. I would say 65 percent of the video was real. It was crazy and a lot of fun.”
