The 21-year-old and her brother Finneas were guests on Jimmy Kimmel Live! and spoke about her career, including the Number One hit from her debut studio album.
Billie Eilish is going through a "different" creative process for her next album.
peaking on Dua Lipa's 'At Your Service' podcast, Billie said of the music making process: "Everything is different about it. I've been trying to compare recently, just because I'm getting used to doing it in a different way. And trying to be like, 'It's OK to do that. I'm OK. I'm still able to do that; I'm capable still.'"

Billie explained: "We were like, 'We've got it all figured out, this is how we're going to do it from now on, and it works really well.'
"And, you know, touring for a year-and-a-half, then coming back to it, and being way older - and not even much older, but again, the jump between 18 and 21 is a big jump."
Billie revealed that she is trying to convince herself that she hasn't "lost it" as her vocals have changed.
She said: "The way that I exist in the room is different, my voice has completely changed since then... The voice-changing thing is a trip! It's all kind of shocking.
The 21-year-old Grammy-winner wrote next to an image of a hand-drawn B in the signature Barbie font, “”What Was I Made For?”
Billie also tagged her brother, Finneas, who is the co-writer to many of her hit songs.
