DJ Samantha Ronson lit up Underground nightclub in Chicago not only with her music, but her LED-lit shoes. She was in town for the Lollapalooza festival and performed Saturday night at the downtown Chicago club for guests including Kellan Lutz, Josh Henderson and “Breaking Bad” actor Aaron Paul. While standing outside with Underground owner Billy Dec after her set, Ronson spotted a street vendor selling glow sticks. She got his attention, bought two and attached them to her shoes.
