Dear Lady Gaga, will you please fill us in on your Fashion Week stamina secrets? Over a month ago we reported the popstar was throwing a major after party with Marc Jacobs and V Magazine, on top of her VMA duties. But today comes news of a third performance, at The Box of course, in honor of the new Givenchy fragrance, Play. It'll be hosted by Out Magazine and Patrick Duffy, featuring an acoustic set of her greatest hits. WWD says The Box is even bringing in a grand piano for the occasion. And you thought the Marc party would be the hardest thing to crash this week.
