Lady Gaga Crashes Pitchfork Festival in Chicago [Pics]

Lady Gaga crashed the 2013 edition of the annual Pitchfork Festival in Chicago. She was there in blonde and high-heeled form last year, seeing her pal Kendrick Lamar. This year, she looked like Joan Jett's doppelganger, with shaggy black hair and a long, loose white rocker tee. Come on, did you really expect Mama Monster to replicate last year's look? Really?

Gaga and her pals were having a good time at the hip event. Check out the semi- shaved head and makeup-free look that Gaga was sporting.

Quick, someone cue up Joan Jett's 'I Love Rock 'n' Roll.' Gaga really looked like Kristen Stewart playing Jett in the movie about The Runaways. We love when she dresses down.

VIP! Here's Gaga and her crew on the side of the stage.

And another shot while on the stage. We like Gaga in full on rocker mode. She looks so normal, but still with that Ma Monster edge.

Rocker Chick! Gaga is a true style chameleon.
