Billie, what went through your mind when you were approached to do the bond title song. Crazy. It's literally been something that phineas and I have wanted to do for year. We knew we wanted the song to be the same title as the film so that was -- we lucked out on the title. It wasn't called cat quantum of solace." Wonderful film title. Wonderful film. Hard song title to write. Solace doesn't rhyme with much. How much creative freedom do you have. Essential total freedom. We didn't want to go in blind and ask fundamental we could have any of the script. We were given part of the script to read. That informed the lyrics. One flaw in the whole thing which was they were there and we were here and they hadn't seen the movie so I said, would you mind jumping onto a plane and sitting in a sweaty little cutting room in the middle of the night completely jet-lagged and watch this movie. Guess what we did? What did you do? That's what we did. I think we did it pretty well. Went right. I think so. I just loved it from the moment I heard it and it just got under my skin and stayed there. Reporter: Eilish says her life feels like a dream. Billie eilish. Billie eilish. Billie eilish.

You were never on my side Reporter: With "No time to die" eilish becomes the youngest to record a track for a bond film joining a list of superstars including Madonna, Adele and Sam Smith. Sam Smith and Adele each have won oscars for their title songs for bond. I'm happy for them. Will we be happy for you at the oscars next year? You performed there this year. All my troubles seemed so far away do you think there's a chance if all goes well that next year at the oscars you'll be there as a nominee and what -- As long as "Frozen 3" doesn't come out, yeah. Hopefully, yeah. I'm excited for next year and this year and every year. I'm really just looking forward to my life. Another milestone for Billie is getting the cover of "Vogue" which I would hold up for you as a prop but I gave my copy to Billie at the end of our interview because she hadn't seen it yet and the James bond film "No time to die" comes out in the U.S. On April 10th.
