Ariana Grande brought back the classic MTV show 'TRL' for one night with 'Total Ariana Live,' where she explained exactly how she ended up in the studio with One Direction’s Harry Styles.

The track penned by the 20-year-old Brit, titled 'A Little Bit of Your Heart,' will feature on Ariana's sophomore album 'My Everything,' set to drop August 25. When asked how she ended up with a song written by Harry specifically for her, she revealed: "I was at the studio one day, and he was there, and literally, Johan [Carlsson] and Savan [Kotecha] were like 'Hey, do you want to write something for Ariana?' And he was like —" she put on a hilarious if not poorly imitated British accent "— ‘Sure, mate.' And he just did."

The 1D member must be as talented at writing as he is at singing, with how much Ariana praised him. "It's a beautiful song. He's an amazing writer," she gushed. "It's really beautiful. He's amazingly talented."

Directioners, Arianators, are you counting down the days 'til you hear this tune?
