The buzz has grown even more after production on the movie wrapped. If Billie works on the soundtrack with her brother Finneas, it would not be their first major movie music project. The siblings previously created music for Barbie and won an Oscar for their work on the film.

Fans quickly took to social media to share their excitement about the possibility of Billie contributing to The Bell Jar soundtrack. Many reacted with comments such as “IS THIS REAL” and “really??? omfg.”

Others were even more excited, with one fan joking about “3 more Oscars” and another expressing disbelief at the idea of Billie writing music for the movie.

Billie, known for hits including Birds of a Feather, was previously rumoured to be working on songs for The Bell Jar with Finneas, but neither sibling has officially confirmed the project.
