Lollalohan: Lindsay Lohan Turns Out For Samantha Ronson Lollapalooza DJ Set

TMZ-land officially arrived at Lollapalooza Saturday afternoon – and you have Mr. Lolla himself, Perry Farrell to thank for it.

A mid-afternoon set at the dance tent Perry’s by Farrell and a “special guest” took on a whole different meaning when that guest was revealed to be none other than Samantha Ronson, accompanied to the endless fascination of all, by her ubiquitous gal pal, Lindsay Lohan. When we arrived to an already packed dance tent, were escorted into a predictably cluster f— of a backstage area, under a searing afternoon sun, and got even more of a celeb eyefull than we were expecting. There was Perry on stage, in a glittery black and white number, spinning and pumping up the crowd for his ‘guest DJ.’ There was LiLo, hanging with a friend and trying not to pay attention to the fact that everyone in the area was looking at her. There was Samantha, waiting to go on. And then there was the even better known member of the Ronson family, DJ and uber producer brother Mark, an attention magnet himself. And to throw a certifiable rock god into the mix, there was the man himself, Slash — yet another surprise guest for Perry to spring on the crowd.

Soon it was showtime for Sam – decked out in an Average White Band t-shirt and a fedora, she spun a 15 minute set heavy on “upbeat” tunes at Perry’s request, she told me, and with a healthy dose of ‘80’s. “Yeah, so I included some Foreigner,” she said, “some Depeche Mode, some Hot Chip. I tried to mix it up.

“I’m just psyched to see Slash,” Sam said of first Lolla experience, “Perry and Slash, I’ve never been to Lollapalooza, and after this I don’t think I need to go to another.” Samantha’s in and out of Chicago – she has to be back in LA tonight – but Mark is hanging all weekend, checking out a ton of favorites — from Black Keys and Radiohead yesterday to Rage tonight — and then playing his own set tomorrow night, on one of the festival’s biggest stages.
