Ten years ago, Billie Eilish was a little girl singing in her bedroom. Today, at the ripe old age of 17, she's still performing songs she made up.
But there's a difference.
This year Eilish released her first album, "When We All Fall Asleep, Where Do We Go?," making one of the biggest debuts in music history. Her #1 song, "Bad Guy," has been streamed more than 3 billion times.
She's the youngest artist ever nominated for all four major Grammy Awards (Album of the Year; Record of the Year and Song of the Year, for "Bad Guy"; and Best New Artist).
To which Billie said, "Growing up, I actually thought I was a terrible songwriter just because he was so good that I was like, 'Oh, I must be terrible if he's that good.' Like, I must be.
"And then he would literally tell me that I was so good at singing, that he thought that he was bad at singing. So, we both had these, like, opposite strengths, we felt like."
For all her new fame and fortune, Billie still lives in the house in which she grew up. (Finneas moved out recently.) Their parents sleep in the living room – that way Billie has a bedroom, and the Finneas bedroom/studio is always available.
On the wall of that room is the songlist, written on a dry-erase board, of what became "When We All Fall Asleep, Where Do We Go?," which they wrote and recorded last year in that bedroom.
But fame has brought darkness into her life. She's been very open about her struggles with anxiety and depression. Becoming an instant worldwide celebrity didn't help.
"I was so unhappy last year," Eilish said. "And even the beginning of this year, I was so unhappy. And I was so, like, joyless."
"Why? Why were you unhappy?" King asked.
"I don't know. I mean, there were so many reasons. It all was because I was actually clinically depressed. That was the beginning of it. But then on top of it was this fame that I didn't want at the time. It was this inability to go out places. And it was so torturous, 'cause all I wanted to do was go hang out with my friends."
Her mother, Maggie, said, "The depression was the hardest part of all this. We checked in with her all the time about, 'Do you still want to do this? Do you want to do this?' She loved doing the shows. That's what kept her going."
Eilish said, "I've been kind of coming out of it for the last, like, six months actually, which feels like that [snaps fingers] to me. But it's, like, the most freeing feeling to be able to come out of that shell."
She says she got through it with therapy, family support. and patience. And she threw herself back into her music.
Back in the studio, Billie and Finneas showed King the birth of a song: "So, a lot of songs, like, start like this, where we're just messing around. He's playing whatever," Eilish said.
The two improvised on the piano and into a microphone. "And you just say words?" King asked.
"Yeah. We just kinda mumble. Like, 'La-na-na-na when no one cares at all. My shoes are off, my hair comes down.' Like, you just make up nothing.
"I literally said, 'My shoes are off, my hair comes down!'" she laughed
At the age of 17 going on 18, Billie Eilish has come a long way without ever really leaving home. Next month, brother and sister are going to the Grammys. Billie has six nominations and Finneas has five. As any teenager might say: "Whatever."
King asked, "Do you feel pressure that you have to top what you've already done, or maintain what you've already done? Do you feel that?"
"Definitely, I feel that," Eilish replied. "But it's not, like, bumming me out. It's not, like, making me super-stressed and, like, worried."
"You look super-stressed and worried, laying there," King noted.
"I know, right? I do, right?" she laughed.
