Billie Joe Armstrong had a rocking good time at Taylor Swift’s Eras Tour this week.

The “American Idiot” rockstar, 52, attended one of the pop icon’s concerts in Lyon, France, and had nothing but good things to share about his experience. “Just saw Taylor Swift eras tour in Lyon France 🇫🇷!!” he wrote in an Instagram caption. “Great production. Great voice. Great entertainer. Great songwriting. Crazy crowd.”

In his post, the Green Day frontman also shared a photo of himself sporting a pair of friendship bracelets he accepted from fans at the show before expressing more gratitude toward Swift.

“Thanks a million @taylorswift,” Armstrong added. “My bracelets say #sexybaby #assh— outlaw.”

The fun of exchanging friendship bracelets has become a pretty notable trend throughout Swift’s live concerts. A gang of fellow celebrities have since hopped on the wave, including Selena Gomez, Halsey, Lance Bass, Sarah Paulson, Lupita Nyong’o, Kumail Nanjiani, Mindy Kaling, Simu Liu, Joe Locke, Mariska Hargitay, Savannah Guthrie, Flavor Flav and now Armstrong.
