Live lip-sync wedding proposal goes viral

Have you ever wondered what would be the most romantic way of popping the question? Actor Isaac Lamb pulled out all of the stops for his girlfriend, Amy Frankel, performing what he deems as the "world's first live lip-dub proposal".

Bruno Mars’ Marry You isn’t a particularly surprising choice for a wedding proposal song, but add 60 friends, perfectly timed choreography and 3.8 million YouTube views, and we‘ve got something special.

It all started with Lamb's brother putting his girlfriend on the back of an open car and telling her that "he wanted to play her a song". Little did she expect millions of viewers would be watching it online.

The Portland actor told The Oregonian: "When I decided to ask Amy to marry me, I wanted something she wouldn't forget".

"I was completely floored," Frankel said: "We had talked about wanting to get married, but I never would have expected that in a million years."
