Hayley Williams & Kacey Musgraves Could Not Deal at the Dashboard Confessional Show

Kacey Musgraves and Paramore's Hayley Williams could not contain their chill on Tuesday night (Feb. 28) at a Dashboard Confessional show in Nashville, where they proudly geeked out over the reunited emo band's biggest hits.

Country star Musgraves, accompanied by fiancé singer Ruston Kelly, posted a video in which she and Williams are singing along to DC's classic early-'00s hit "Screaming Infidelities," like everyone at The Basement East was watching.

Williams wasn't too cool to fan girl out, either. She also posted a clip where she was "feeling my feelins'" at the show, during an acoustic run through "The Swiss Army Romance."
