The movie No Time to Die, the 25th title in the James Bond motion picture franchise, is due to arrive in theaters in April, with Daniel Craig resuming his title role as the British secret agent for a fifth and final time.
Eilish is slated to perform the theme song live for the first time at the Brit Awards in London Feb. 18, ahead of the March 9 launch of her North American arena tour, Interscope said in a statement.
She had widely been expected to debut the Bond single at the Academy Awards show on Sunday, but she sang the Beatles' "Yesterday" during the telecast's in memoriam segment instead.
Two weeks earlier Eilish swept the Grammys by taking the four top prizes - best album, best record, song of the year and best new artist - becoming only the second musician to win all four categories on the same night.
Eilish wrote and recorded most of her debut studio album, When We Fall Asleep, Where Do We Go? - with her brother, Finneas, 22, in the small bedroom of their Los Angeles-area home.
The album, including such hits as When the Party's Over, Everything I Wanted and Bad Guy, ranked as the No. 1 album of 2019.
