Where did Chelsea Clinton and Marc Mezvinsky learn the Dancing with the Stars-like moves they displayed on their wedding day? They had some professional help.
Maksim Chmerkovskiy, a pro dancer on DWTS, choreographed the couple’s first dance, PEOPLE reports in this week’s issue.
Clinton, 30, and her groom, 32, made a big splash at their July 31 reception with a sultry first dance.
“It was an amazing, funny, unexpected dance,” a friend of the bride’s tells PEOPLE. “Bill and Hillary seemed to love it.”
