Jordan Moreau Hayley Williams, the lead singer of rock band Paramore, and Lil Uzi Vert, the Philly rapper behind “Just Wanna Rock” and more, have been fans of each other for a long time, but it wasn’t until Wednesday night at Madison Square Garden that they finally met. The mutual adoration started in January 2016 when Uzi posted a video of himself on Twitter singing along with Paramore’s hit song “Ain’t It Fun.” At the time, Uzi was still an up-and-coming rapper with a few catchy tracks under his belt, but Williams must have taken note. Over the years, they traded compliments for each other — Uzi named her his dream collaboration and that “there’s no one better than Hayley Williams” in a recent Complex interview, and Williams revealed the two had talked about a collab that never came to fruition — until the two took the stage together in New York City.
