Billie Eilish is taking over the music industry faster than even she could have ever imagined. The singer first started out when she was only 15 years old, and considering how tough the industry is, she's dealt with it like a champion.

Eilish's songs are currently sitting comfortably in the top 10 spots of every major music chart, which is quite the feat for the now 17-year-old singer. Despite only having three albums, her most recent landing at number one, Eilish has graced fans worldwide with her hit songs and countless fashion looks.

Billie has managed to befriend numerous big names in the business, many of which claim to be huge fans of the singer! From Julia Roberts, Justin Bieber and Ariana Grande, here is a list of 14 celebrities who love Billie Eilish, and a few who aren't as lucky to be friends with her.
