On Tuesday, the production companies behind No Time to Die announced that the 18-year-old singer will sing its theme song, making her the youngest musician ever to do a theme song for the James Bond franchise. Eilish wrote the song with her brother, Finneas O'Connell, and has thus become the youngest artist to perform and write a Bond track.
"It feels crazy to be a part of this in every way," Eilish said in a press release. "To be able to score the theme song to a film that is part of such a legendary series is a huge honor. James Bond is the coolest film franchise ever to exist. I’m still in shock."
"Writing the theme song for a Bond film is something we’ve been dreaming about doing our entire lives," O'Connell added. "There is no more iconic pairing of music and cinema than the likes of Goldfinger and Live and Let Die. We feel so so lucky to play a small role in such a legendary franchise, long live 007."
Additionally, the film's director, Cary Fukunaga, said, "There are a chosen few who record a Bond theme. I am a huge fan of Billie and Finneas. Their creative integrity and talent are second to none and I cannot wait for audiences to hear what they’ve brought -- a fresh new perspective whose vocals will echo for generations to come."
Fans initially speculated that Eilish would be the next singer when she took to her Instagram Story to share photos of past Bond girls including Halle Berry and Eva Green.
An additional clue of Eilish's involvement came thanks to some sleuthing fans, who discovered that Fukunaga, the director of No Time to Die, follows both Eilish and her brother on Instagram. Many thought the clue was significant due to the fact that Fukunaga only follows 81 people on the social media site.

The announcement followed speculation from Beyoncé fans that she'd be the one to sing the No Time to Die track. That suggestion took off after the singer shared a shot of herself drinking a martini, 007's favorite drink, at the Golden Globes.
The trailer for the flick dropped early last month and featured 007 leaping off ancient stone bridges, firing at oncoming assailants with high-tech hidden guns in his Aston Martin and contending with a new mysterious masked villain, played by none other than Rami Malek.
When ET caught up with the movie's star, Daniel Craig, in April, he said this will likely be his last Bond film.
"This is going to be my last Bond, I think," he said. "I think I've done enough, people are going to get sick of the sight of me. Someone else should have a go."'
