Billie Eilish has blown up over the past year and if you don't remember how quickly it's happened, watch this.

Vanity Fair interview Eilish last month, exactly a year after they last interviewed her and decided to ask her all the same questions.

Eilish was 15 at the time of the first interview and now she's 16 with millions of followers and famous friends. It doesn't necessarily mean she's happier though.

The end result is a really honest and emotional display of the toll of fame and also just the turmoils of growing up.

It's a really great video piece. Watch it below.
