Vocal sensation Ariana Grande has revealed that One Direction heartthrob Harry Styles wrote a song that features on her upcoming new album called 'Just A Little Bit of Your Heart'. 

Speaking to MTV's TRL in a one-off special entitled 'Total Ariana Live', the beauty explained that he happened to be in the studio at the same time as her so it just worked out that they could collaborate:

"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."

The 'Problem' songstress went onto praise Styles' songwriting abilities, adding: "It's a beautiful song. He's an amazing writer. It's really beautiful. He's amazingly talented."

Grande's new album is called 'My Everything' and it's due to be officially released on August 25.
