Earlier this week, Billie Eilish was fangirling over Avril Lavigne on Pitchfork's latest episode of Over/Under on their YouTube channel, The Inquisitr reported.
Since then Eilish met Lavigne backstage at one of her shows.
"Avril was everything to me dude, I love Avril. I only love her. There's nothing else there, just love," she explained to Pitchfork.
"There is almost no other artist like that. Her, Tyler, Gambino, [Justin] Bieber to be honest made me and Lana, probably," the "You Should See Me In A Crown" hitmaker continued.
"[Avril] has my number though and she texts me sometimes, it's so cool. She'll be like: 'Hey babe it's Avril xo'. Oh my God," she said.
Skip to a couple of days later when Billie was hanging out with Avril in person while causing a storm on social media.

Avril looks super happy to have met Billie, sparking a huge grin. She was wearing a short-sleeved KISS T-shirt. Her blonde hair was straight which made the singer look very youthful.

"IM SCREAMING WHAT THE HELL," Fifth Harmony's Lauren Jauregui commented.
"'Sk8er Boi' changed my life," rapper Rejjie Snow shared.
