I'm backstage at Ellen dressed up in disguise

and I'm very embarrassed about it.

I love these babies.

I'm going to go up, and I'm going to surprise them,

and they're not going to know it's me,

but it is going to be me.

OK, let's go.

Stand between the white lines, all right?

There's two more coming?

Do you mind if my daughter does one?

No, go ahead.

That's fine.

All right, go ahead sweetie.

All right you guys, make sure you're

in between the white lines there.

And then you're going to look right here at this camera.

I love those shoes.

We're here to see Billie Eilish perform.

To see Billie!

She's an icon.

I can listen to her anytime of the day, every single second.

I went and saw her in concert at Camp Flog Gnaw.

It was so insane.

I love her authenticity.

She doesn't shy away from her anxiety.

She just puts it forth in her music.

She's unapologetic.

She's very honest.

Her voice is like an angel--

like an angel.

I know.

Her music has helped me through a lot.

This depression and anxiety too-- like her music

makes me feel less alone just by listening to her.

Because I know she goes through the same things too.

And she's very open about it.

If you could say one thing to her, what would you say to her?

Keep doing what you're doing.

Like don't change.

I love you so much.

Oh my god.

She's an inspiration to so many girls and boys everywhere.

I love you.

Yeah, I would just tell her how much she's impacted my life

and how much I love her.

Thank you.

You're amazing.

I love you.

I love you.

I love you.

You're amazing.

You're a queen.

Thank you.

Do you want to maybe tell her that?

Yes!

[SCREAMING]

Oh my god!

[INTERPOSING VOICES]

I'm crying so much.

We were just so nervous, we didn't even see her!

[LAUGHTER]

[INTERPOSING VOICES]

Do you see my outfit?

Great disguise.

You think?

Yeah.

Very true to yourself.

I'm so glad--

I was like, why aren't you saying anything?

Have you seen me wear pants like this ever?

[INTERPOSING VOICES]

I love you.

I can't believe this is happening.

I'm literally shaking.

I literally can't.

We need a group hug.

Come here.

Oh my god.

I like group hugs.

Oh my god.

Oh my god.

That was so cute.

That was a moment.

That's not your father.

No, not at all.

[LAUGHTER]

Thank you guys for being here.

I appreciate this.

Thank you.

All right, I love you all.

That was the most amazing thing ever.

I've seen so many of these videos

and I'm always like, how do people not

know that's the famous person?

And I was just praying--

You never know until it's happening to you.

Thank you, Billie!
