Hardy, 36, who has been engaged to Riley for three years, apparently referred to his actress partner as "wife" on the red carpet of his film 'Locke' in New York on April 24, reported Us magazine.
"Well my wife is an actor as well so she sort of gets it. She's just a very kind, pure person. Apart from that, I'm a pain sometimes really. You know what I mean? Like any other boyfriend. Isn't that part of being in a relationship?," he said at the event.
