Flash mob proposal at Sundial in St. Petersburg

A flash mob led up to a surprise proposal in St. Petersburg and it was all caught on video.

The video of the flash mob coming together on the Sundial courtyard in downtown St. Pete was posted by the Sundial on Facebook. 

The dancers, coordinated by FYI Dance Company and made up of dancers, family, and friends of the couple, began to come together to the song "Can't Stop the Feeling" by Justin Timberlake in the courtyard.

Eventually the groom-to-be, Alex DeJesus, struts through the crowd dressed to the nines where he greets his girlfriend, Kacy Nastari, and gets down on one knee.

There were lots of cheers and tears as she said yes!
