" In the wake of the tremendous heat, stylish Lollapalooza attendees waged on \u2014 sporting their best looks for the three days of music insanity. Without question, Chicago&amp;#039;s Lollapalooza is known for it&amp;#039;s diversity in music so it&amp;#039;s no surprise that artists such as Lady Gaga, Green Day, Phoenix, and MGMT all took the stage. Between the bohemian chic and the &amp;#039;80s revival, the crowd was certianly eye-catching to say the least. Girls wore long maxi dresses, short shorts, patterned bikini tops, braided headbands, and loose rompers that were a cute spin on a modern hippie. Others, however, opted to take the rocker aspect of the festival to the next level. From their tatterted skinny jeans to bright colored tanks and bold accessories, these girls looked ready to rock.   Although the festival itself was packed with a fabulous group of musicians, the celebrities all came out for the Hard Rock Hotel&amp;#039;s annual &amp;quot;Music Lounge.&amp;quot; The event kicked off Thursday night at Perez Hilton&amp;#039;s &amp;quot;One Night in Chicago&amp;quot; party where he was spotted dancing his heart out to songs from B.O.B, Kid Sister, Lissie Nneka, and J Brazil. Also at the lounge was Ke$ha and her new boyfriend, musician Alex Carapetis, as well as Hayden Panettiere, Jessica Stroup, David Arquette, and Mike Posner. At the lounge, celebs picked up cute shades from Carrera, awesome clothing from Express, and even were able to get tattoos! Between the festival and the music lounge, the entire event couldn&amp;#039;t have been more fun!     "^^<http://www.w3.org/2001/XMLSchema#string>
