Millie Bobby Brown had a no-nonsense moment while striking a pose at the Stranger Things season 5 screening in London on Thursday, November 13. As she gave the camera a stunning pout, a photographer shouted at the actress to smile. "Smile? You smile!" she responded while pointing to the group of photographers, per People. Brown then turned away from the cameras and exited the carpet. For the premiere, Brown looked gorgeous in an Ashi Studio dress featuring a structured corset with exposed boning.
