Saturday Night Live

NBC | 11:29 pm

Singer-songwriter Billie Eilish — the youngest artist in Grammy Award history to win all four general field categories (record, song and album of the year, plus best new artist) in the same year — pulls double duty as she makes her debut as host of this Emmy-winning comedy series, while also returning as the night's musical guest. She joins such performers as Nick Jonas, Stevie Wonder, Willie Nelson, Britney Spears, Justin Timberlake and Paul Simon in serving in both these capacities.
