Lady Gaga to Perform at Lollapalooza

The lineup for Lollapalooza has been announced—and it's going to be quite a summer. Lady Gaga will headline the August festival in Chicag—a far cry from 2007, when she performed at a small side-stage at the festival. Other bands who'll hit the stages include: MGMT, Green Day, Spoon, Grizzly Bear, Devo, Cypress Hill, Arcade Fire, the Strokes, Erykah Badu, and Phoenix. The concert is scheduled for August 5-8.
