Leave it to Lady Gaga to turn Lollapalooza into a one-woman lingerie show.

Hours before her star turn on the stage at Grant Park in Chicago last night, the divine Lady G. showed up at a performance by Semi-Precious Weapons dressed in typical festival gear — a shredded fishnet matching top and tights, gold pasties and dollar-store sunglasses.

Somewhere backstage, Taylor Momsen was probably taking notes.

If you’re reading this Monday morning and you’re not in Chicago, you are almost certainly thinking the same thing I am: why, oh why, didn’t I go?!?!
