Lady Gaga [1] kept the sexy outings [2] coming on Monday when she attended Brandon Maxwell's show at New York Fashion Week. Rocking an all-black outfit and a long ponytail, the "Perfect Illusion [3]" singer looked like her fierce self as she posed for photographers during the event. Not only did she mingle with the designer, who is also her longtime friend, but she even reunited with her American Horror Story [4] costar, Naomi Campbell [5]. A few hours later, she channeled her inner Rihanna [6] by walking around the city while sipping on some Champagne [7].
