No, this isn't some romantic One Direction fan fiction. This is real life, people! Harry Styles has written a new song for Ariana Grande's upcoming album and girlfriend can't stop gushing over how gorgeous it is.

Last night during her TRL resurrection special on MTV, the rising-pop princess revealed that a new song off her forthcoming My Everything LP, "A Little Bit of Your Heart," was penned by the 1D heartthrob.

''It's a beautiful song," Ari said of the track. "He's an amazing writer. It's really beautiful. He's amazingly talented.’'

But how difficult was it to land the in-demand "It boy"? Not that hard, according to Ariana. ''I was at the studio one day and he was there, and literally, [One Direction 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."

"A Little Bit of Your Heart" joins Ariana's smash hit "Problem" and her just-unveiled EDM banger "Break Free" on My Everything, out this fall. Read more about the LP and its ultra-hip collaborators right here.
