Singer-songwriter Ed Sheeran is penning songs for Taylor Swift.
Swift is said to be "into British music" and is a "massive fan" of the A Team singer, and requested that he write some fresh material for her.
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 is not known if he will be credited on Swift's new album, but will indeed make a substantial sum for his work.
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, he tweeted about working in the studio which some say hints at Swift.
He tweeted: "writing songs with a very cool artist today :) (sic)"
