The 21-year-old singer songwriter is claimed by The Sun newspaper to have been out in the States, working in the studio with massively successful Taylor.
A source told the paper: "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'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."
The paper claims that a co-writing credit on just one track could net Ed £200k - and that Taylor has sold 22 million albums globally.
Earlier this month Ed quit his US tour for "personal reasons".
