The Strictly Come Dancing crew aren't the only ones who know how to shake their stuff on the dancefloor.
Crown Princess Mary and her husband Prince Frederik showed off their fancy footwork at a ball in New York recently.
Mary's face shone with delight as her husband twirled her round at the chic function in the Hilton Hotel.
The mum-of-four was elegant in a floor length nude-hued gown.
The fun-loving couple were letting their hair down at a function to celebrate 100 years of the American-Scandinavian Foundation, which promotes good relations between the two countries.
