Watch Billie Eilish and Finneas O'Connell's Intimate Grammys Performance

From ELLE

Billie Eilish made her Grammys performance debut in the most vocally beautiful of ways, of course. The singer performed "When the Party's Over" with her brother Finneas O'Connell. He played the piano, and they matched in white suits. They had a sweet brother-sister moment at the end, when the song was over, he applauded her, and they stepped off stage together.

Eilish is nominated for six awards tonight: Record of the Year ("Bad Guy"), Album of the Year (When We All Fall Asleep, Where Do We Go?), Song of the Year ("Bad Guy"), Best New Artist, Best Pop Solo Performance ("Bad Guy"), and Best Pop Vocal Album (When We All Fall Asleep, Where Do We Go?). It's her first time ever attending the ceremony.

When Eilish first learned about her nominations, she was elated and floored, she told Jimmy Kimmel on his show in November. "As cool as everything else is, it's the Grammys. I've watched that every single year of my entire life, like judging all the girls' ugly-ass dresses," she said, teasingly. "Every year my family and me, we would all sit in the living room and watch the Grammys. We never missed it. The fact that I'm the same little girl watching that in my living room, and then I'm still in that same living room being nominated for six! What is that?"

She also talked to ELLE in September about her devotion to delivering her best performances and never canceling last minute. “I would rather not do a show than do a mediocre version. I am one thousand percent serious,” she said. "I’m telling you: I’m never going to cancel a show the day of. If I do, someone is allowed to slap me in the face. If I die? Okay, I get it. Buck up, Billie. Get the fuck up on that stage, and do your shit.”
