Watching Billie Eilish live out every Belieber fangirl dream had us EMOTIONAL 🥹 Knowing how die hard of a fan she was as a kid made this moment so heartfelt. We’re so happy for her and love Justin for making it happen. 💜✨ 🎥: monica.mejiaaa #bieberchella #justinbieber #billieeilish #onelesslonelygirl #coachella
