William "Mack" Knight
Emma quietly dated the Silicon Valley manager for nearly two years, starting in 2015. The actress was extremely protective of their relationship and refused to talk about him in interviews. "I can't talk about my boyfriend in an interview," Emma previously told Vanity Fair. "I've noticed, in Hollywood, who you're dating gets tied up into your film promotion and becomes part of the performance and the circus. I would hate anyone that I were with to feel like they were in any way part of a show or an act."
