Michael Fassbender refused to answer questions regarding his romance with Alicia Vikander in a new interview.
The couple has been dating for two years, but very rarely talk about its relationship, which reportedly began while filming new movie, The Light Between Oceans.
And when the actors were quizzed about their love life in a joint interview with Entertainment Tonight, Fassbender was quick to shut down the questioning.
"I'm not going to talk about my private life with a total stranger, unless I feel like I need to. Why would I? I don't," he retorted.
Vikander, however, sweetly deflected the question with a more diplomatic response than her 39-year-old Irishman beau.
"I think we've made a clear statement that we keep certain things just between us," she said. "It was very easy to unite, but that's quite personal."
The Light Between Oceans, adapted from the M.L. Stedman novel of the same name, follows the story of a lighthouse keeper and his wife who decide to raise a baby they rescue from an adrift rowboat.
The stars portray husband and wife onscreen, but Michael was keen to dispel reports they had fallen in love while filming the Derek Cianfrance movie back in 2014.
"It wasn't the first time in a movie either of us had played somebody who is falling in love. There is an element of separation there. If I'm playing a murderer, I don't go out and start murdering people," he said sarcastically.
The Light Between Oceans is released on 2 September (16).
