While the full Lollapalooza lineup won’t be officially announced until April — with the festival going down in Chicago on August 6–8 — some excitable blabbermouth has spilled the beans on the headliners to the Daily Swarm.

While you wait for confirmation, entertain yourself with these photos of a brunette, unfamous Gaga’s appearance at the fest in 2007. [DailySwarm]
