This is Serena Williams' favorite Green Day song, according to Billie Joe Armstrong

Green Day is generally best known for Grammy-winning record of the year "Boulevard Of Broken Dreams" or top-10 Hot 100 single "Wake Me Up When September Ends," but Serena Williams is a big enough fan of the punk rock band that she prefers the deep cuts.

Frontman Billie Joe Armstrong joined Jimmy Kimmel Live for Tuesday night's episode to promote his new Audible project Welcome To My Panic (out Thursday), but the conversation eventually veered toward Williams' fandom.

Kimmel recalled the time he invited the tennis icon to the show to meet Green Day, which paid off for him at the 2012 London Olympics. 

"She was playing in the Olympics that day at Wimbledon and gave us a tour—a lengthy tour—of Wimbledon on the day she was playing," Kimmel told the 49-year-old musician, "and I was like, 'You don't have to do this!' I was panicking that maybe she might lose because she's not focused. She's like, 'No, no. You introduced me to Green Day, so I owe you.' And then she won the gold medal."

"She's great," Armstrong replied. "We would run into her in different countries in Europe because she was kicking everybody's a— in that particular country. ... I think she would literally try to see how fast she could beat her opponent so she could actually come to the gig. She would end up showing up, and she would always ask for us to play the song 'Disappearing Boy.'"
