Billie Eilish took the stage at the Greek Theatre in Los Angeles on Thursday (July 11), where she came face-to-face with one of her childhood idols.
The 17-year-old superstar took to Instagram to share a photo she took backstage with Avril Lavigne. "THANK YOU FOR MAKING ME WHAT I AM," she wrote in the caption. It's clear where Eilish has drawn inspiration from the pop veteran, both decked in edgy attire with angsty lyrics.
