The 18-year-old singer, who has been dating Gomez for a while now, narrated the lyrics to his friend Will.I.Am on a flight, reported Aceshowbiz.
"He taps me on the shoulder... 'Yo, I want to show you this song I produced and wrote. I'm really excited about it because it's one of the first songs I produced by myself'.
"The song was dope. He was like, 'Yeah, I wrote it for Selena. It's great.' And it was really awesome. It was, like, really, really dope," Will.I.Am said.
The Black Eyed Peas rapper says that as a producer himself, it makes him proud to see someone so interested in producing and songwriting just as he is.
"I think that guy is gonna be around for a really, really long time," he added.
