I know you're at "Saturday Night Live,"

and that's how you first know me, right?

From "Saturday Night Live." -Did you hear about that?

-No. -So, okay, listen.

When I was growing up -- I mean, I am 17,

but when I was like... Really, like 5 or 4

or more or 3 -- I don't know.

I used to watch a show called "The Electric Company,"

and -- [ Laughs ] There was a guy on it,

and he had eyeliner, and he was singing about H's

'cause it was, like, a little kids show,

and he was like -- the hook was like --

What is it? It was like "My H's," like...

Something, something, nothing -- I don't even know what it was,

but it was you, and then I remember seeing you on TV,

and I was like, "That's the guy

from the commercial with the H's."

[ Laughter ]

-It's such a long career.

-I got a pocket full of H's, and I'm not afraid to use them.

-Yeah, pocket full of H's. It was like a Ramones

type of song. -And it was you!

-♪ I got a pocket full of H's, and I'm not afraid to use them ♪

But no one saw that in my whole lifetime.

[ Laughter ] -But I thought --

-I made movies, I was on "Saturday Night Live" for years.

"Weekend Update" -- hello!

-So, like, when I was on this show, like, a while ago...

-You didn't know me from "Saturday Night Live"?

-No. [ Laughter ]

-That's what I heard that you did.

-I was so excited to meet you because...

-That's hilarious. They all told me

that you knew me from -- you got a story

about "Saturday Night Live." Oh, my gosh.

I can't believe you saw that. [ Laughter ]

Oh, my God. No one saw that.

And I was, like -- I was pulling H's

out of my pocket and throwing them and stuff.

-Yeah, you were. You had thick eyeliner.

-Let's talk about you. [ Laughter ]

-Let's talk about your music right here.

Look at this -- "When We Fall Asleep, Where Do We Go"

is the biggest selling debut album in a decade.

You're the first female artist --

[ Cheers and applause ]

You're the first female artist

to have 14 simultaneous chart entries.

Your music and videos have been streamed 15 billion times.

[ Cheers and applause ]

That's you! That's you I'm talking about.

I got to say, the album is so great.

Everyone loves it. Your fans are young,

they're old, they're all sorts of people.

Why do you think this music resonates

with so many different people?

-Um...I mean, it was, like, a big goal,

so I feel like I'm -- I don't know why necessarily.

I just think I'm mainly happy about it.

I think, like, I grew up listening to so much

different kind of music, like, old stuff and new stuff

and hip-hop and contemporary and then jazz and Peggy Lee,

Frank Sinatra and then Tyler the Creator

and, like, Nas. -Yeah.

-I was all over the place, and I think I just put it

into my music.

And with the album, specifically,

there was one thing I really tried to do,

which was that -- There are like 14 songs

on the album, and one of the goals I had

was I wanted to make an album that I could put

14 people into a room that each had, like, fully different,

fully different tastes -- like, one person like this,

one person like this, and that's all they liked,

and that if I played them my album,

each person would like at least one song.

-Wow. That's a really cool way of attacking it.

And you did it. I mean, I heard it.

I think I heard "Bad Guy" first, and I was like,

"I don't know if anyone's ready for this type of music."

It was so different. I was like --

-I didn't, either. I thought they'd hate it.

-I didn't know why. I was like, "Is this..."

Dude, you changed the face of pop music

and music, in general, 'cause we were hearing the same song

for the last three years, and you just played something

totally different, like, pwkk! And I was like --

Now we're gonna hear nothing but songs like "Bad Guy"

for the next three years.

Because that's all -- It was good.

-Thank you so much.

-I love the whole record. -That's really sweet.

-Which one -- Just tell me,

which one do you think would go to me out of these 14?

-Would go to you? -Yeah. What number am I?

-What number are you? -Yeah, in this album.

-Oh. -Mm-hmm.

-I mean, you just made it pretty clear that you're "Bad Guy."

[ Laughter ] So 2.

-It was a trick question. Yeah, you're right.

I like that. But I'm a good guy.

-You are a good guy. -Thank you, yeah.

-A good bad guy. -I am, yeah.

-I want to talk about this thing happening right here.

-Yes, sir. -What's going on?

You sprained your ankle, or what's happening?

-Look at my little sock. -Yeah.

-Um, yeah, I sprained this. You know, what's funny

is they're actually both sprained.

This is like -- -What?

-Three weeks old, four weeks old.

This one is like two months old.

Hilarious. -How do you -- how did you --

[ Laughter ]

But how did you sprain your ankle,

and how do you perform with a sprained ankle?

-I just wear this, and I pretend it's not sprained.

[ Laughter ]

I sprained it in the lawn like 3 seconds into the show.

For real. Like, I walked on stage and sprained it.

-Walking? How hard do you walk?

-I jumped. One leg -- -There you go.

-It was the sixth count into "Bad Guy."

It was, like, literally the sixth count --

♪ Bum, ba da da, buh buh -- ♪

-And that's where you did it.

-Why? You stood up.

You really stood up. -I was ready to get into it.

I was ready to jump. -You was about to jump.

-I was ready to jump, and that's it.

Now I sprained my ankle just now.

I just sprained -- I sprained both of my ankles.

-It wasn't only just embarrassing

that I sprained it.

It was more embarrassing that I, like, fell.

You know what I'm saying? Who falls, you know?

[ Laughter ] Embarrassing.

-You didn't tell me you fell.

So, you went for it, and then you fell.

But did people think it was part of the dance?

-Probably. [ Laughter ]

Or they just were like, "Pfft! She fell."

Like, that's what I was worried about,

that they were like, "Loser, she fell."

-No. -But, really, I was, like,

laying there in agonizing pain.

Thing is, I have sprained this leg -- or, this ankle

like five times before, so I knew exactly what it was.

-Maybe you're wearing the wrong footwear.

[ Laughter ]

-I actually was wearing -- That's crazy you say that.

I was wearing a pair of shoes I had never performed in.

-You got to bring me on tour with you.

-Yeah, I do. I do!

-Talk about the new world tour.

Can you believe you're going on a world tour,

Billie Eilish, 17 years old?

[ Cheers and applause ]

That's what I'm talking about! That's how you do it!

But you're doing something different

and cool with this tour.

Talk about the green part of this tour.

-Yes. Well, basically, we just announced today,

as you just said, it's the Where Do We Go World Tour.

-The Where Do We Go World Tour. -Where Do We Go World Tour.

And, basically, we're trying to be

as, like, green as possible on the entire tour.

So, there's, like -- We're actually bringing someone

from Reverb, this company that basically specializes --

Is that a word? -Yeah.

-Okay. -"Reverb" or "specializes"?

-Specializes. -Specializes.

Reverb, I'd be like, "Oh, is that...?"

Yeah, but Reverb. -Specializes in, like,

the best and most healthy and green ways to do everything.

So there's no plastic straws allowed,

the fans are gonna bring their own water bottles,

there's gonna be recycle cans everywhere.

'Cause it's like, if something's recyclable,

it doesn't matter unless there's a recycle bin, you know?

It doesn't do anything unless there is one.

-Don't want just recycled trash everywhere.

You're actually gonna recycle everything.

-Yeah. -I love that you're doing this.

You're doing so many great things.

I love it. -Thank you.

[ Cheers and applause ]

I'm psyched to have you back. Come back whenever you want.

Do we know what songs you're doing on "SNL"?

Can you say, or...? -Ooh!

-I actually haven't said, but I can say.

-You can? -I don't know if I can.

-Why not, right? What songs you gonna do?

-This is live. -Yeah, we're too late.

-A little too late.

You know what? I don't care, so why not?

I'm doing "Bad Guy" and "I Love You."

-Oh, my gosh! Come on.

So watch that Saturday! Billie Eilish tomorrow night.

[ Cheers and applause ]

Yeah, give her a standing ovation. Why not?
