The 51-year-old pop star was one of the first in the celebrity world to shorten her name to a few letters. In a new interview, she finally revealed who inspired her to do this. It turns out that the authorship belongs to the late rapper Heavy D., who helped J. Lo record his debut album On the 6. By the time of its release (1999), Jennifer Lopez was already famous as an actress.

“Heavy D. often dropped in the studio when I was recording my first album and called me Jenny-Lo, Jennifer-Lo or J. Lo,” the singer told InStyle magazine. “When I was working on the second album, I decided to call it J. Lo, and I think that’s when the nickname stuck.”

Judy Greer, who shone with Jen in The Wedding Planner, remembered that the star was called Jen-Lo on the set. A romcom with Matthew McConaughey in the lead male role was released in January 2001. In the same year, Lopez admitted in an interview with the Chicago Tribune that she owes her nickname to fans: “I come to MTV or somewhere, and there are always kids with posters of J. Lo. It’s kind of like street terminology, and it seems to have stuck. “
