Hear the haunting new track from her highly anticipated film debut.
Can you even believe it?! Just when we thought we knew what Billie Eilish was up to, she goes and pulls another one of her signature surprises. Today, Friday, September 11, 2026, the 24-year-old global superstar dropped a brand-new, haunting single, “Under the Bell,” out of nowhere! This isn’t just any new song though; it’s the very first piece of music from her upcoming film debut, “The Bell Jar,” where she stars as Esther Greenwood. Fans everywhere are totally freaking out, and trust me, you’ll want to hear this track to get a taste of what’s to come in her huge new acting role!
THE FULL STORY
Billie Eilish, the Grammy-winning sensation, stunned the music world this morning by releasing “Under the Bell” with absolutely no warning. The track, a moody and atmospheric masterpiece, immediately hit all major streaming platforms like Spotify, Apple Music, and Amazon Music. It’s a direct tie-in to her highly anticipated acting debut in “The Bell Jar,” an adaptation of Sylvia Plath’s iconic novel, which just wrapped filming on September 8, 2026. The song perfectly captures the intense, introspective mood that fans expect from the film’s subject matter.
Billie herself shared a cryptic post on her Instagram, @billieeilish, just moments before the song dropped. The post featured a black-and-white image of a bell jar, with a single tear rolling down the glass. Her caption simply read, “For Esther. Under the Bell. Out now.” She followed up with a story, sharing, “I couldn’t believe it when they told me the film was wrapped. Creating this song felt like breathing life into Esther’s soul, and I just had to share it now. It’s literally a dream come true to bring her story to the screen and to music.” The single was, of course, co-written and produced with her incredibly talented older brother, Finneas O’Connell.
This surprise release is a classic Billie move, reminiscent of her “no singles” approach for her critically acclaimed 2024 album, “Hit Me Hard and Soft”. This time, it’s a single, but the element of surprise is still very much there, and it’s making waves across pop culture.
BACKSTORY/CONTEXT
This new single builds on a super busy and successful period for Billie. Her third studio album, “Hit Me Hard and Soft,” released on May 17, 2024, was a massive hit, topping charts in over 20 countries. She then embarked on the “Hit Me Hard and Soft: The Tour,” which saw her play over 100 shows across North America, Europe, Australia, and Japan, finally wrapping up on November 23, 2025. You might remember the incredible 3D concert film, “Billie Eilish , Hit Me Hard and Soft: The Tour (Live in 3D),” co-directed with Oscar winner James Cameron, which hit theaters earlier this year on May 8, 2026.
Earlier this year, in February 2026, Billie and Finneas made history at the 68th Grammy Awards. They won Song of the Year for “Wildflower,” a track from “Hit Me Hard and Soft,” becoming the first artists ever to win that prestigious award three times! They previously won for “Bad Guy” in 2020 and “What Was I Made For?” in 2024. Billie also used her platform at the Grammys to make a powerful statement against immigration authorities, saying, “No one is illegal on stolen land.”
Then came the big news about her acting debut in “The Bell Jar.” Focus Features confirmed on September 8, 2026, that filming had officially wrapped for the adaptation, with Billie starring as the protagonist, Esther Greenwood. Speculation about her contributing music to the film has been swirling for months. While Billie confirmed in May 2026 that her fourth studio album wouldn’t arrive until 2027, this surprise single doesn’t contradict that, instead giving fans a taste of her musical genius intertwined with her acting journey.
FAN & SOCIAL MEDIA REACTION
As you can imagine, the internet exploded! Within minutes of Billie’s Instagram post, “#UnderTheBell” and “#BillieBellJar” were trending worldwide on X (formerly Twitter). Fans were quick to share their shock and excitement.
“I literally screamed when I saw the notification! Billie never disappoints with a surprise drop! #UnderTheBell” tweeted @EilishFanatic. Another fan, @GreenwoodVibes, shared, “The lyrics for ‘Under the Bell’ are so raw, it’s already giving me chills thinking about ‘The Bell Jar’ movie. This is going to be epic. 😩” Memes instantly popped up, with one viral image showing a fan looking overwhelmed with joy, captioned, “Me listening to Billie’s new song and remembering her acting debut is coming. My heart can’t take it! 😭”
Even some of her celebrity peers chimed in. Fellow artist Halsey posted, “Queen of surprises! Always pushing boundaries, @billieeilish. This track is everything. So excited for #TheBellJar.” Of course, Finneas, her brother and collaborator, shared his sister’s post with a simple yet heartfelt, “So proud. She truly poured her heart into this one.”
INSIDER DETAILS
Sources close to the production of “The Bell Jar” revealed that “Under the Bell” was largely conceived during short breaks in filming. “Billie was so immersed in the character of Esther that the music just flowed naturally,” one source exclusively told us. “She and Finneas had a portable setup on set, and they would just go straight into recording ideas after intense scenes. It was incredible to watch her transition from actor to musician so seamlessly.”
This creative process allowed Billie to channel Esther’s emotions directly into the song, creating an authentic connection between the music and the film. While this single is out now, there’s a strong buzz that more original music from Billie and Finneas will be featured in the full soundtrack for “The Bell Jar.” “You can definitely expect more musical surprises as we get closer to the film’s release,” our source teased.
Speaking of Finneas, he’s had a pretty big year himself! Just recently, on August 29, 2026, Billie officiated his wedding to actress Claudia Sulewski in Montecito, California. Claudia, 30, recently shared in a YouTube video that they chose Billie for the role because “He wanted her to be his best man, and I wanted her to be my maid of honor. So we thought, ‘Okay, sounds like she needs to marry us.'” It’s clear that family bond is stronger than ever, both personally and creatively.
WHAT IT MEANS
This surprise single marks a powerful moment for Billie Eilish, firmly cementing her dual presence in both the music and film industries. It shows her unique ability to blend her profound musical artistry with her new venture into acting, proving she’s not just a musician dabbling in film, but a true multi-hyphenate artist. “Under the Bell” serves as a crucial bridge, introducing fans to the emotional depth of “The Bell Jar” before they even see the movie.
Fans can now expect a truly immersive experience with “The Bell Jar,” knowing that Billie’s musical voice will be woven into the fabric of the story. This release also sets a high bar for other artists looking to cross over into film, demonstrating how to do it with authenticity and impact.
