Ariana Grande has revealed that One Direction's Harry Styles penned a song for her upcoming new album.
The singer told MTV's TRL about how the song, entitled A Little Bit Of Your Heart, came to be: "I was at the studio one day and he was there, and literally, [songwriters] Johan [Carlsson] and Savan [Kotecha] were like 'Hey, do you want to write something for Ariana?'
"'And he was like, 'Sure, mate'. And he just did.'"
Grande's album My Everything is set for release on August 25.
