Last week, Madonna finally dropped her album Hard Candy and every able-bodied New Yorker came out to the Roseland in Manhattan to watch the diva perform her hot new dance tracks.

Decked out in head-to-toe Dolce & Gabbana athletic gear, Madge performed her hit "4 minutes on stage with Justin Timberlake" while a slew of CFDA babes like Donna Karan, Jack McCollough and Lazaro Hernandez of Proenza Schouler, Harvey Weinstein, Lyor Cohen, Tory Burch and Rosie O'Donnell danced along.

Meanwhile, right after her live performance, Madonna slipped on a Ralph Lauren frock and headed over to friend/photographer Steven Klein's birthday party at The Box where waiters walked around in Dolce & Gabbana underwear all night.

And who said you were suppose to start slowing down at 50?
