The Definitive Guide to Billie Eilish's Sesame Street Appearance

The question of whether Billie Eilish appeared on Sesame Street is answered with a resounding "yes," and the details are a perfect blend of the pop star's moody aesthetic and the show's educational mission. Her episode was a highlight of the show's 52nd season, which premiered in late 2021 and ran through 2022 on HBO Max and PBS Kids.

1. She Performed a Counting-Themed Parody of "Happier Than Ever"

Instead of a straightforward musical performance, Eilish collaborated with one of the most iconic Muppets for a fun, educational parody. She sang a special version of her hit single, "Happier Than Ever," which was the title track from her second studio album. The song was cleverly rewritten to focus entirely on the concept of counting, a classic Sesame Street educational theme. This creative reimagining of the song maintained the melody and emotional core of the original while making it perfectly suitable for a preschool audience.

2. Her Muppet Co-Star Was The Count

It's no surprise that a song about counting would feature the show's resident number-loving vampire, The Count (Count von Count). The segment featured Eilish and The Count enthusiastically counting various objects, from blocks and apples to bats—a nod to The Count's vampiric nature. The Count’s signature laugh and enthusiastic "Ah ah ah!" added a layer of comedy to Eilish's usually serious delivery, creating a delightful contrast that was praised by critics and fans alike. The chemistry between the two was a central part of the segment’s success.

3. The Episode Aired in Mid-2022

While Sesame Street's 52nd season premiered in November 2021 on HBO Max, Billie Eilish's specific episode, titled "Elmo's Number Adventure," aired on June 16, 2022. The anticipation for the segment built up for months, with a short clip of her and The Count being released ahead of the full episode premiere. This timing placed her appearance shortly after the massive success of her Happier Than Ever album and world tour, cementing her status as a global cultural phenomenon.

4. She Followed in the Footsteps of Other Major Musicians

Billie Eilish is part of a long and distinguished tradition of musical heavyweights who have graced Sesame Street. The 52nd season alone featured other major musical guests, including country star Kacey Musgraves and hip-hop artist Anderson .Paak. Other past guests have included Katy Perry, Ed Sheeran, Bruno Mars, and even legends like Johnny Cash and Stevie Wonder. Eilish’s willingness to participate underscores the show's enduring cultural relevance and its ability to attract A-list talent for its educational mission.

5. Her Brother Finneas Was Not Officially Part of the Main Duet

While Billie Eilish and her brother/producer Finneas O'Connell are an inseparable musical duo, the main, widely-publicized "Happier Than Ever" duet was a solo effort by Billie alongside The Count. Finneas was not featured in that specific counting segment. However, the siblings have a history of working on projects appealing to a younger demographic, and their joint creative efforts are a constant presence in Billie's career, making the association with family-friendly content a natural fit for her brand.
