But he was at Harper Bazaar and he had no other reason to be there and before the rumors started didn’t he also attend another event with her? I’m scared for Viceroy’s House events!

Believe it or not, HB is in a marketing partnership with The Crown. He was here because of that. There were probably other people from this show in the room, so no, he wasn’t there for her.
Don’t be scared, we might as well have an answer before the Premiere.
