While Tom Petty's official 2013 touring calendar is still empty, it's been confirmed he'll headline the Hangout Music Festival in Gulf Shores, Ala. this spring. The full lineup for the festival was announced this week, with Kings of Leon named as a second headliner for the three-day festival.

This follows late-December rumors that Petty and the Heartbreakers would headline Bonnaroo 2013. The lineup for that festival has yet to be revealed. According to a YouTube video starring Weird Al Yankovic, that announcement will be made on Feb. 19.

All tickets for Hangout 2013 will go on sale Feb. 15 at 10AM. Additional acts performing include the Black Crowes, Trey Anastasio Band, the Roots, Public Enemy and Gov't Mule. The fourth annual Hangout Music Festival takes place May 17-19. Previous headliners for the beach party have included Red Hot Chili Peppers, Foo Fighters and Paul Simon.
