Eilish confirmed that it was just that deep saying she "would watch the music video for this song and just sob."

"I just want to say, we did consider taking you to therapy because you were in so much pain over Justin Bieber," her mother joked.

Cell phone cameras were there to record the moment when the young Grammy winner met Bieber for the first time last year at Coachella.

Bieber's manager, Scooter Braun, shared video of the meeting which resulted in a big hug between the pair.

"She finally met the kid," Braun tweeted.
