Paramore's set at the Austin City Limits Festival Sunday coincided with Red Hot Chili Peppers bassist Flea's 60th birthday, and the "Misery Business" trio took a moment to celebrate the occasion.

During the show, frontwoman Hayley Williams sang "Happy Birthday" to Flea, riffing "I've loved you since I was eight-years-old and it was really inappropriate" during the "Happy birthday dear..." part.

You can watch fan-shot footage of the performance posted by YouTube user RHCPtv1.

Rage Against the Machine's Tom Morello also wished Flea a happy 60th Sunday on Instagram, calling the bassist a "total BEAST of a player and a big hearted human."

The Peppers, meanwhile, just released a new album, Return of the Dream Canteen, last Friday. It's the second RHCP record of 2022 following April's Unlimited Love. The band's U.S. tour concluded over the weekend with their headlining set at ACL.
