Taylor Swift and Ed Sheeran are known to be firm friends. 

The pair have previously collaborated together on one of their most successful songs to date, Everything Has Changed.

With that in mind, it wasn't all that surprising when rumours began swirling that Sheeran might make an appearance on Taylor's brand new album.

Taylor's hotly anticipated new album Reputation has been in the works for month, with a pretty amazing social media promotion behind it. 

It was on Swift's Instagram that fans first saw the news that Ed Sheeran would be featuring on one of her new songs. 

The track list shows that song two, End Game, is a collaboration between Taylor and Ed.

Rapper Future will also make an appearance on the track.

We're dying to hear the pair's latest collab.
