She first showed off her new locks in an Instagram post last week. The singer posted the SNL tease on her Instagram and captioned it, “SNL! SEE YOU ON SATURDAY???? .”<\/p>\n In the SNL promo, Eilish and McKinnon<\/strong> do a bit about the singer’s upcoming 20th birthday, McKinnon<\/strong> talking Eilish’s ear off about simultaneously playing two different characters in the same sketch and McKinnon fawning over a “mischievous Norwegian Christmas gnome” who sneaks into her apartment and ties her cats’ tails together. Good times!<\/p>\n Eilish, of course, is not the first artist to pull double duty as guest host and musical guest. Miley Cyrus, Adele, Justin Timberlake, Harry Styles and Chance the Rapper are just some who have also done the same.<\/p>\n \u00a0<\/p>\n\n\n Billie Eilish pulls double duty as host and musical guest on Saturday Night Live on December 11, 2021.<\/p>\n\n\nKate McKinnon Reveals a Big Birthday Secret to Billie Eilish – SNL<\/h2>\n\n\n
