Ed Sheeran has revealed that he thought he was gay growing up because he has "a big feminine side".

The singer, 30, said that his interests, which he believes to be "feminine", made him wonder about his sexuality when he "was a kid".

"I have a definite feminine side, to the point that, when I was a kid, I thought I was gay for a bit," he told Dutch podcast Man, Man, Man.

The 'Shape of You' hitmaker went on: "I definitely have a big feminine side - I love musical theatre, I love pop music, I love Britney Spears."

"My masculine side probably stops at drinking beer and watching football. I am not a car guy. I like a nice car, but I'm not a car guy," he added.

Sheeran is married to childhood sweetheart Cherry Seaborn and the couple share daughter, Lyra, who is 15-months-old.

It comes as Sheeran was called a "f**king big mouth" by Elton John after he leaked the news of a surprise Christmas duet, per NME.

Sheeran spoke about the collab during his appearance on the Dutch radio station, NPO Radio 2, earlier this week — to the dismay of the Rocket Man singer.

The 74-year-old told NME: "Yeah, he let the cat out of the bag, didn't he?"

"I was sworn to secrecy and then big mouth f**king Sheeran goes to the Netherlands! It's supposed to come out – we haven't finished it yet, so there's still work to be done," he added.

The track in question currently does not have a title or release date.

During his interview with NPO Radio 2, Sheeran disclosed that the idea for the duet was John's idea.

He reportedly called him last year after Sheeran's Christmas song, Step into Christmas, charted in the UK Top 10.

"Elton rang me on Christmas Day to say Merry Christmas. Elton rings me almost every single day," he told the radio station. "He said, 'Step Into Christmas is Number 6 in the charts! I want to do another Christmas song – will you do it with me?"

Initially, however, Sheeran admitted that he "didn't feel like [the track] suited him."

But, having the opportunity to work with such a legendary pop star helped to sway him. "It's just me and him. It's great," he added.
