A West Hollywood man's birthday surprise turned out to be a marriage proposal.

In a video posted earlier this week, actor Lucas Bane pulls out all the stops to create a memorable marriage proposal for his boyfriend, David Devora.

Lucas has gathered the couple's friends for a surprise birthday party for David.

“Happy birthday,” they all shout as a blindfolded David arrives across the street from the couple's apartment, where a “Happy B-Day David!” sign hangs from the lit balcony.

Actress Briana Evigan (Step Up 2: The Streets) and a troupe of dancers stomp to Pitbull's Timber on the sidewalk.

Then Lucas appears on the balcony and the music switches to Bruno Mars' Marry You.

He holds up a sign that says, “Our lives will be perfect, if we spend them together,” then removes the birthday sign to reveal “Will U Marry Me” in lights. (The video is embedded on this page. Visit our video library for more videos.)
