Well, this is rather surprising. Tinashe (who prior to this, had no experience as a ghostwriter for pop stars) has revealed that she originally wrote Jennifer Lopez's comeback single "I Luh Ya Papi."

In a new article published by FADER, Matthew Trammell recounts how Tinashe visited the office yesterday and spilled the beans. On the song's origins, she said:

"It wasn’t 'Papi' at first, it was 'I Luh You Nigga,' like, 'I luh ya luh ya luh ya nigga.' They switched the swag up a little bit! It was intended for Aquarius and everything. Then Detail was in a session with J. Lo and he played her the track, because you know these producers sometimes, they’re like 'Yo, lemme play you my hot shit!' I guess she obviously really liked it, and she cut her version. One day Detail calls me and is like 'B-T-dubs, J. Lo is singing that song.' I didn’t believe it at first, I thought he was just not trying to give it to me for some reason. I was like 'J. Lo does not want that song, she’s not gonna sing that.' And then it came out. I guess she wanted it."
