Because why don't guys get asked about their make up removal and what they're planning on wearing on the red carpet?
Let me remind you of one of the first press conferences for The Avengers when Scarlett rightfully snapped at a reporter:
Reporter: “I have a question to Robert and to Scarlett. Firstly to Robert, throughout Iron Man 1 and 2, Tony Stark started off as a very egotistical character but learns how to fight as a team. And so how did you approach this role, bearing in mind that kind of maturity as a human being when it comes to the Tony Stark character, and did you learn anything throughout the three movies that you made? And to Scarlett, to get into shape for Black Widow did you have anything special to do in terms of the diet, like did you have to eat any specific food, or that sort of thing?"
Scarlett: “How come you get the really interesting existential question, and I get the like, “rabbit food” question?”
