Sunny Days, Billie Eilish Is Chasin’ the Clouds Away...Performing 'Happier Than Ever' As An Ode To Counting In 'Sesame Street' Teaser.

"Billie Eilish's full Sesame Street episode has yet to air, but the show gave her fans both young and old a taste of what to expect by sharing a clip of her performing a modified version of her Billboard Hot 100 hit "Happier Than Ever" on Tuesday (Nov. 9).

For the children-appropriate version of the song, Eilish took to the Sesame Street steps to teach kids how to count with assistance from Count von Count. "When I'm counting with you/ I'm happier than ever/ Numbers sound so much better/ Here's what we'll do/ Come on, let's count to two/ One, two of Burt's sweaters/ One, two heads are together/ Come on, let's count to two," Eilish and the Count take turns singing.

"Happier Than Ever" has so far peaked at No. 11 on the Billboard Hot 100, while her album of the same named topped the Billboard 200.

Eilish is one of many celebrities to guest star on Sesame Street's 52nd season. On Nov. 4, the long-running children's program announced that musicians Kacey Musgraves, Anderson .Paak and Jon Batiste will have appearances on the show, which is set to return to HBO Max on Thursday. The show shot some of the upcoming episodes on location outside its soundstage due to the COVID-19 pandemic.

“Creating this season of Sesame Street during the pandemic has been an enormous undertaking,” said Ben Lehmann, Sesame Workshop’s senior vice president & head of live action and Sesame Street executive producer in a statement. “Just as our characters use playful problem-solving in the face of challenges, we, too, took a creative approach, finding innovative solutions while keeping our cast and crew safe. We’re proud of what we’ve been able to produce and are grateful to our partners at WarnerMedia and PBS for their continued support of Sesame Street.”
