The couple showed off moves inspired by the finale in the 1987 film while partying at Z100's Jingle Ball at Madison Square Garden in New York on Friday.
The One Direction hunk gamely picked Swift up by the waist and hoisted her above his head, recreating the classic movie moment when Patrick Swayze lifted co-star Jennifer Grey into the air.
An onlooker posted a photo of the pair dancing on Twitter, writing: "Harry Styles gives Taylor Swift a 'lift' at the One Direction MSG After Party!"
A source tells The Sun: "It was brilliant. The song came on and they just started dancing together. They didn't know it from start to finish, but towards the end they had a little chat, then she took a run and jumped in to his arms. Everyone was laughing and egging them on."
