All About That Bass hitmaker Meghan Trainor has revealed that she was joined in the recording studio by One Direction's Harry Styles to record a duet.

The singer told The Sun of their collaboration Someday Maybe, "It's real! It's a duet.

"It's a beautiful song we wrote together on my ukulele. We even recorded a rough demo together with our vocals together. It's a cute acoustic love thing."

Trainor added that she was afraid Styles wouldn't be a very good song writer, "It's one of the first cool things I got to do with a pop star. A friend of mine said Harry was a fan and said he would love to write with me.

"He's an incredible writer, too. I was worried he'd just be a 20-year-old boy. So I walked in with a prepared verse and chorus. But he gave me very poetic, mature lyrics. I was like, 'Well, damn, Harry, you know what love is'."

Unfortunately however she added that the song may never be released.

Styles has previously written with Kodaline and Ariana Grande.
