An epic wedding surprise for one lucky bride is going viral, and once you watch these moves, you'll see why.

Sean Rajaee and his seven groomsmen put on a performance for the ages at his June 21 wedding in Palos Verdes, California, dancing to a medley of Beyoncé, Bruno Mars - and the bride's personal favorite-The Backstreet Boys.

"When I saw a lot of his moves it took me back to our childhood days because I'd force him to listen to Beyoncé and 'N Sync," the groom's sister, Shirin Rajaee, who was also the maid of honor, told ABC News.

Some of the groomsmen had flown in from around the country so they had to learn the routine through a video tutorial, but that didn't slow them down.

"My brother is an orthopedic surgeon," said Rajaee. "It's interesting because a lot of people that know him from the medical world would be like, 'Oh my gosh.' But he's a fun, funny kind of guy. The fact he got he got all the groomsmen to do it and to go along with it was crazy. A lot of them were coming from long distance."

Needless to say, the bride was totally blown away.
