Wedding proposals are meant to be memorable, and in the case of this British couple, the bride to be will never forget how her boyfriend proposed.

With the help of a flash mob and Bruno Mars' song "Marry You", Pete and Siobhan are now engaged. While vacationing in New York City, the couple went for a stroll through Central Park and came upon a group of people who were dancing to the Bruno Mars song where Pete ended up joining in the flash mob matching them move for move. At the end of the dance, he walks over to propose to his girlfriend, who says, "YES!"

Pete organized the whole thing with the help of a company called Flash Mob America. He told the British paper, The Sun:

Basically, I knew that Siobhan loved flash mobs. I just wanted to do something really different. I couldn't think of anything else that would suit her. I was so nervous.  When I started the dance it went totally out of my head. I wasn't even sure when I was [supposed] to join in."
