Sharing a name isn't the only thing Billie Joe Armstrong has in common with Billie Eilish -- they're also both big fans of The Office.
The Green Day frontman shared his love for all things Dunder Mifflin in a new installment of the Office Ladies podcast, in which cast members Jenna Fischer and Angela Kinsey -- who played the characters Pam Beesly and Angela Martin, respectively -- look back at each episode of the beloved sitcom.
The topic for this week was the season six episode "Secret Santa," which, as Office fans may recall, features a karaoke rendition of the Green Day song "Boulevard of Broken Dreams," as sung by Rainn Wilson's Dwight Schrute and Ed Helms' Andy Bernard.
In honor of the Green Day and The Office crossover, Armstrong sent Office Ladies a recording of him giving the "Secret Santa" episode remake. He also shared how he felt "completely taken by surprise" seeing "Boulevard of Broken Dreams" being performed on the show.
"Andy, he started singing harmonies...we do have a musical for American Idiot, and he sang the same exact harmony that's in the musical," Armstrong said. "It was good."
In addition to watching The Office, Armstrong is getting ready to return to the road with Green Day. Their 2022 live schedule includes sets at Lollapalooza, Shaky Knees and Outside Lands, among other festivals, as well as the European leg of the Hella Mega tour with Weezer and Fall Out Boy.
