Solange Knowles

Beyonce’s sister, Solange Knowles, performed her single “Bad Girls” at a Brooklyn, New York Atlantis laundromat. The 27-year-old singer and DJ Looked a little dead behind the eyes — probably due to medications she allegedly takes to control a rumored mood disorder. Despite the rumors surrounding recent cancellation of Solange’s European concert tour, observers report that she was lucid and lively during the Laundromat show.

Solange tried her best to look sexy while singing as loaded commercial size washers hummed in the background. Solo’s concert was sponsored by Vitamin Water and THE FADER as part of the “Make Boring Brilliant” campaign. Surprisingly there were no laundry detergent sponsors.
