The entire lineup for Lollapalooza 2012 has apparently been leaked online.

I had heard the plan was to release the list on April 11th (Wednesday), but looks like someone working for Lollapalooza had another idea. Rumor has it someone got their hands on a copy of the lineup, took a picture of it, and posted it online for all to see.

This is what many are passing as an official lineup to this summer's premiere festival in Chicago, but it has not been confirmed.

I've been to Lollapalooza a few times, but not in several years. Always a cool festival to check out if you've never been. 

Looks like the main headliners are Red Hot Chili Peppers, The Black Keys, & Black Sabbath. Jack White and Florence & The Machine are also included in the main big acts.

If you were thinking of going to the festival, are you happy with this year's lineup?

Update: So the list was accurate. Lollapalooza has posted the official lineup.
