New York, New York - Amid the continued success of her Barbie collaboration, Billie Eilish has teased her next music moves as she dished on her highly-anticipated third album.

The 21-year-old stopped by The Tonight Show on Thursday, where she chatted about her latest single, What Was I Made For?, from the soundtrack of the Barbie movie.

While the track is still enjoying success on the charts several months after its release, Billie did tease her current work on a new project.

"We are almost done with this new album we're working on," she told host Jimmy Fallon.

The Grammy winner remained tight-lipped about further details, adding, "At some point, you will know more, but I'm not going to say anything else."

The Ocean Eyes artist previously opened up about her next record in an interview back in September, similarly confirming she was "in the final stages of making it."

Elsewhere in her late-night appearance, Billie gushed over her collaboration with Barbie director Greta Gerwig as she and her brother, Finneas, drew inspiration from the titular character's storyline to pen the emotional track.

"I felt like it brought women together in this way that I feel like I haven't felt part of like that, and it made me feel really good," Billie said of the movie.

"And I also felt like it was bringing people together. It felt like we were all experiencing the life experience, you know?"

What Was I Made For? recently scored a Golden Globe nomination for Best Original Song for a Motion Picture, joining the track's five Grammy Award nominations, including Song of the Year.

Billie is expected to perform the track live as the musical guest on this week's episode of Saturday Night Live.
