Hiddleston, who previously datedTaylor Swift, explained why he doesn’t discuss romantic relationships during a 2017 interview withThe Telegraph, saying, “Everyone is entitled to a private life.”

“I love what I do and I dedicate myself with absolute commitment to making great art and great entertainment, and in my mind I don’t conflict the two. My work is in the public sphere and I have a private life. And those two things are separate.”
