Following One Direction's momentous concert at New York City's Madison Square Garden, the lads headed to an afterparty to relax and found themselves doing karaoke.

A video has surfaced of the lads performing an entertaining rendition of Elton John and Kiki Dee's 'Don't Go Breaking My Heart', but also joining them on the night was singer-songwriter Ed Sheeran who had performed with the lads earlier at the venue.

Taylor Swift, who has been photographed both in the U.S. and UK with heartthrob Harry Styles over the past few weeks, can also be seen dancing with the group in the clip.

Earlier this week, a picture emerged of Styles lifting Swift into the air in a 'Dirty Dancing' recreation, which was shortly followed by a brief video of the pair watching bands backstage together and enjoying a quick kiss at the Z-100 Jingle Ball.
