Ed Sheeran has made Harry Styles the envy of many men, after joking about the size of his manhood.

The Thinking Out Loud singer inadvertently shared more than fans expected after he revealed his song Little Things, which he wrote for One Direction’s 2012 album Take Me Home, is definitely not about Harry or any part of his anatomy.

“[Harry] definitely hasn’t got a little thing, so no, I did not write Little Things about little things,” Ed told New Zealand magazine ZM.

The 24-year-old also revealed that his One Direction friend may have leaked his own naked photo.

The picture, which showed a man with his face obscured flashing in front of a mirror, made it big online in 2012.

“Did you know Harry leaked that picture himself?” Ed said. “He leaked his own picture… I think it’s amazing. He was just like, ‘no one knows’.”

Ed also said he would be happy for his friend Taylor Swift to date Calvin Harris. The pair have been linked, since they were photographed together at a Hollywood gig.

“Yeah, I’d give the seal of approval… There are just certain people who are just nice people in the industry. I met [Calvin] like a year ago… Really good guy.”
