The pair were joined by Ed Sheeran and One Direction members following their Madison Square Garden gig.
One Direction's Harry Styles and his rumoured girlfriend Taylor Swift did karaoke together following the group's performance at Madison Square Garden in New York last night (3rd December).
The pair partied together along with other members of the group and Ed Sheeran at the after show party.
In a picture posted online, Harry and Taylor are seen standing close together, while Ed Sheeran performs a cover of a Backstreet Boys song. Niall Horan is also on the stage with the pop stars.
The picture of Harry and Taylor together comes in the same week that the pair enjoyed a public outing together at New York's Central Park zoo.
The pair have yet to confirm reports that they are dating, but fans have already dubbed them Haylor in honour of the relationship.
One Direction played the biggest gig of their lives at Madison Square Garden last night, where they were joined on stage by Ed Sheeran for 'Little Things'.
The group delighted the crowd with a set of the past hits and songs from new album 'Take Me Home'.
