Ed Sheeran Breaks Down One Direction, Taylor Swift Collaborations

British singer/songwriter says he was surprised by 'how cool' Swift is.

If you still don't know who 21-year-old British singer/songwriter Ed Sheeran is, then you might want to bone up. The folkie up-and-comer is already being embraced by some of the biggest pop acts on the planet as he launches a full-on U.S. invasion of his own.

Having already worked with the boys of One Direction on their album Up All Night, he revealed he's going to work with the guys again later this summer as they prep their sophomore release.

"I wrote a couple of songs when I was 17 that One Direction want for their next album," he said, via Perez Hilton. "I'm going into the studio in August to produce the tracks for them."

In addition to working with the British boy banders, he also recently hit the studio with Taylor Swift, as she prepares her follow-up to Speak Now, her smash 2010 release.

"It's such a pleasure to have people like her in the music industry — she has the talent and is so down to earth, head and shoulders," he told Pop Crush, adding that he was surprised by "just how cool she was."

He went on to say that he was taken aback by her maturity when they hit the studio together. "I've never really met acts like [her]. You meet people like Elton [John] who have been in the game for 30-40 years who are wise and old and been at it for a long time — and Taylor's been in it for six years and she's 22," he explained. "And you hear horror stories about younger musicians who kind of go a bit off the rails, but she's so together and so kind of professional and knows what she wants, but ... isn't too harsh — she's just a really sweet gentle person — so yeah, that's what surprised me, is that she was sound."

Sheeran recently dropped his own debut album, +, Stateside, where he landed at #5 on the Billboard Hot 200 chart.
