After Solange exchanged vows with Alan Ferguson in New Orleans on Sunday, she and her 10-year-old son Daniel Julez entertained guests at her wedding reception with a three-minute dance-off to “No Flex Zone.”

Both dressed in white, they performed choreographed moves and challenged each other in front of guests including Beyoncé, Jay Z, and Janelle Monáe. They ended their routine with a big hug as everyone cheered.
