Lollapalooza hasn’t announced the full lineup to their August festival yet, but we may already know the headliners. Greg Kot of the Chicago Tribune is reporting that the festival’s organizers have decided on Eminem, Kings of Leon, Arctic Monkeys, and Skrillex as the headliners for this year’s festival.

All four rumored headliners have appeared at the festival before, and two of them have headlined Lollapalooza in the past (Eminem in 2011, Kings of Leon in 2009). This would be the first headlining stint for Skrillex, the punk singer turned EDM producer, or the British megastars Arctic Monkeys.

Last year, more than 300,000 people attended Lollapalooza. This year’s festival will take place on August 1st through 3rd at Chicago’s Grant Park.
