Ed Sheeran has revealed that he has a new Taylor Swift duet sitting on his phone.

The British singer-songwriter featured on the country-pop star's 2012 record 'Red' in the shape of collaboration 'Everything Has Changed'.

However, the 'Lego House' man told MTV that the duo have recorded another track - which is currently on his mobile phone. He said:

"We did a lot of stuff, but I don't know whose record it will end up on. We did three songs, and recorded two, and one went on her album, which is the next single."

Sheeran added: "But we'll see what happens with the other one. There's no specific plan so far, it's just chilling on my iTunes right now, it's on my phone!'."

The 'A Team' man meanwhile is currently supporting Swift on her North American 'Red' tour.
