Ed Sheeran writing for Taylor Swift

Ed Sheeran has been writing songs for Taylor Swift.

The 'A Team' hitmaker - who has previously penned tracks for One Direction - was asked by the country singer to work on her new album because she is a 'massive fan' of his own music.

A source told The Sun newspaper: 'Ed and Taylor have been in the studio in LA a lot over the past few weeks working on new material.

'She's into her British music and became a massive fan of Ed before asking to work with him recently.

'There is a mutual affection between the pair.'

It has not yet been decided whether Ed's songs will be released as singles, but even just a credit on an album track will earn the 21-year-old British star around 200,000.

The source added: 'It's still to be officially decided how the material will be released but just a single credit on her album will be worth big money.

'Taylor's country sound is massive around the world.'

Earlier this month, Ed revealed he was working with a 'cool' artist while in Los Angeles.

He tweeted: 'writing songs with a very cool artist today :) (sic)'
