LOS ANGELES, April 7 (UPI) -- Kesha appeared at Petty Fest last week and performed for the first time since she left rehab.
Petty Fest honors the music of Tom Petty, and Kesha surprised audience members when she stepped on stage to cover "Free Fallin'" during the event. The 27-year-old singer took the microphone to audience applause, and proceeded to give an impromptu and emotional rendition of the song.
