Taylor Swift has posted a video of herself performing with Ed Sheeran online.

The short video, which was posted on Twitter, sees Sheeran on guitar playing his hit track 'Lego House' whilst Swift sits cross-legged singing.

It enjoys a homemade quality and looks like the pair, who are joined by another female, are playing in a house.

As previously reported, Sheeran and Swift have been writing together, although it is unclear yet what form the collaboration will take.

Sheeran meanwhile has also previously said that he has been involved in writing sessions with Northern Irish band Snow Patrol. Watch Ed Sheeran and Taylor Swift perform 'Lego House' below:
