Chanel Iman told us what really happens inside the Met Gala. “I have to tell you a secret,” the model admitted in her custom J. Mendel gown and Lorraine Schwartz jewels. “The real party is in the girls’ bathroom . . . the younger girls will go in and we all have chitchat and catch up. Then we go back to the performance,” she explained. “You’ll find models and actresses and, like [male designer] Alexander Wang. Everyone has a good time in the bathroom.” Wait, Wang? “He’s allowed, I guess!” Iman added, “Honestly, it’s really fun.”
