As the crowd of over 1600 cleared Roseland Ballroom, Madonna
made her way to the DJ booth to dance with her producer and hand-picked DJ Martin Solveig. Those who stuck around were lucky enough to join in the dance party with the Material Girl herself, jamming to songs like Jay-Z's Empire State of Mind
and Madonna's own song, HungUp
. Also spotted getting into the groove? Madonna's boyfriend Brahim Zaibat and daughter Lourdes.
