Billie Eilish reflected on her career in a new video from Vanity Fair. It's amazing to see how far she has come at such a young age. A 15-year-old Billie sat down to answer a series of questions - that they then asked her on the same day three years in a row.

Billie said making sure she's happy is the most important thing in her life right now.

It's amazing to see how much she's blown up in just three years.
