Marc Jacobs proposes to boyfriend Char Defrancesco with a flash mob at Chipotle

The designer proposed with the help of a flash mob at a Chipotle restaurant.

The fashion designer surprised his longtime boyfriend Char "Charly" Defrancesco, a model turned candlemaker, with a proposal over dinner at a Chipotle restaurant Wednesday night.

But this was no ordinary weeknight dinner. Defrancesco was treated to both a dinner and a show, when a flash mob of dancers broke into a performance to Prince's "Kiss."

After the dancers finished, Jacobs dropped to one knee in front of Defrancesco.

The whole thing was caught on video, which Jacobs posted to Instagram.

"And this happened...'Charly Defrancesco will you marry me'? #flashmobatchipotle #moves THANK YOU everyone for making this happen video @plural_nyc @laurengerrie @seandon212 @1.800.newbold And to my Ride or Die fiancé @chardefrancesco I LOVE YOU" he wrote alongside the video.

The pair have been linked for two years. In addition to getting engaged, they celebrated Defrancesco's birthday on Wednesday. Jacobs will celebrate his 55th birthday on April 9.
