Perry Farrell is firing back at "an anonymous Lollapalooza insider" that has been leaking the annual music festival's lineup via Twitter. The rumored lineup features Metallica, Red Hot Chili Peppers, Beyonce, and more.

A Twitter account under the handle @lollaleaks began posting what it claimed would be the lineup for this year's festival earlier this month. Some of the acts "leaked" include headliners Metallica, Red Hot Chili Peppers, and Beyonce along with Korn, Missy Elliott, Garbage, AWOLNATION, the Gaslight Anthem, The Killers, Beck, YACHT, the Big Pink, Wild Flag, Ben Folds Five, and a final performance from Sonic Youth.

Festival creator and Jane's Addiction vocalist Perry Farrell has been engaged in a Twitter war with the self proclaimed "insider," calling the leaker a "red tick," "a fraud," and also assuming the mystery person "must have a small penis." Farrell further stated that the festival's lineup was not finalized, the real lineup is expected to be announced this April. Lollapalooza will take place August 3rd-5th in Chicago's Grant Park.
