Perry Farrell, Lollapalooza: Jane's Addiction Frontman Calls Lineup Leaker 'Fraud'

Lollapalooza founder and Jane's Addiction singer Perry Farrell is fed up with people concocting rumours about the lineup for this year's festival.

On Friday, Farrell got into a testy exchange on Twitter with a person named "LollaLeaks," an "anonymous Lollapalooza insider" who earlier that day tweeted: "I'm doing a headliner at 10:00 tonight. I'll be releasing a few more acts throughout the day."

Farrell replied: "I am a lonely lier."

When another fan asked Farrell how to explain somebody like "LollaLeaks," the musician tweeted: "How do U explain sex offenders?"

The pointed barb got the attention of "LollaLeaks," who tweeted: "I think comparing me to sex offenders is a little steep."

From there, "LollaLeaks" threatened to release "all of the headliners" for Lollapalooza which Farrell again replied to with: "You must have a small penis." He then asked "LollaLeaks" to move on to other matters and predict the winners at the Grammy Awards. The musician later tweeted that the insider should seek a "Dr. for the brains."

On Sunday night, Farrell again dismissed any possible lineup "LollaLeaks" was reporting. "NO! Folks, Lolla line up has not been finalized," he tweeted. "He's a fraud."

Lollapalooza's official site says that the lineup and ticket information will be released this spring. The festival is slated for Chicago's Grant Park Aug. 3-5. Last year's lineup featured Foo Fighters, Eminem, Coldplay and Muse, among others.

Meanwhile, a Brazilian version of Lollapalooza is set for Sao Paulo April 7-8 with Foo Fighters, Arctic Monkeys and Jane's Addiction as the main headliners alongside other acts like Skrillex and Cage the Elephant. A Lollapalooza is also confirmed for Santiago, Chile March 31-April 1 with Foo Fighters, Arctic Monkeys and Bjork headlining.

With so much going on in the Lolla world, it's a wonder Farrell even has time to call out this Twitter-happy "Lollaleaks" character.
