Beyoncé Knowles and her pal Kelly Rowland hung out at Oakdale Mobile Home Park in South Brunswick, NJ, last night to shoot a new music video! They were decked out in sequins and fur to record the visuals for "Party," a track off Beyoncé's album 4, with Solange Knowles there, too. A lot of the action centered around Beyoncé singing in an Airstream, surrounded by brightly dressed dancers. It was an evening of working on her own music for Beyoncé after she spent Tuesday focusing on Jay-Z's. Beyoncé and Kelly went to a Watch the Throne listening party thrown by Jay and Kanye West at the Hayden Planetarium.
