Darkroom/Interscope's Billie Eilish joined the Saturday Night Live double-threat club when she both hosted and performed over the weekend. The Grammy winner's episode featured TikTok dances, weird Santa, a rocking "Happier Than Ever" and more, with assists from friends and family.

As she's done throughout her career, Eilish kicked it family-style on Saturday—her mother, Maggie, appeared in the opening monologue and returned alongside her father, Patrick, to introduce her first musical performance, while brother/producer FINNEAS appeared in multiple skits. Miley Cyrus also made a guest appearance.

Eilish and her creative team employed some camera tricks for her presentation of Record and Song of the Year nominee "Happier Than Ever," which started its soft introduction in a makeshift room, then panned to reveal the audience and ended with Eilish's rocking out with FINNEAS and her band.
