Lady Gaga rocks fiercest look yet at epic makeup line launch party

Lady Gaga launched her beauty brand with an epic “Haus Party” on September 16, proving she knows how to rock a Monday. The 33-year-old megastar toasted to her new venture Haus Laboratories before a crowd of 500 guests inside of the sweeping Barker Hangar event space in Santa Monica, California. A true hostess with the mostess, LG spoke inspirationally, popped champagne, took to the DJ station and served up three of her fiercest looks yet (the final one pictured here)

Lady Gaga took to the DJ booth at one point, spinning some of her own music and favorite songs.

The A Star Is Born leading lady treated onlookers to not one, but three modish black ensembles. Seen here, she made simple carpet walk in a sparkling Jessica Rabbit-like dress, which featured a high-slit to flaunt her toned legs.

Later, as she ascended a staircase onto a dark stage to address the room, she rocked a black patent oversized motorcycle jacket atop a black bodysuit and thigh high stockings inside of platform boots.
