Billie Eilish launches her own signature ukulele.

Billie Eilish has teamed up with Fender to create her very own signature ukulele - adorned of course, with her Blohsh symbol - which was the first instrument she ever learned.

About the instrument, Eilish says: "The rules of ukulele are: If you know three chords, you know every song. Ever. You can play any song."
