Tom Hiddleston's Pal Benedict Cumberbatch Refuses to Ask Him About Taylor Swift: 'That Door Is Closed'

The actor chatted with Benedict Cumberbatch, who defended his right to a private life.

While fans are eager to know more about the cause of Tom Hiddleston and Taylor Swift's breakup, the 36-year-old actor kept mum about his three-month relationship with the "Shake It Off" singer.

Hiddleston chats with pal Benedict Cumberbatch for Interview magazine, and does not speak about Swift because he's not asked about her. "There’s another weight of us being in the public eye, which is this presumption that, because your work and your promotion work is very public, your private life should be, too," Cumberbatch explains. "I just want to say that I’m not going to ask questions about my friend’s personal life just because there are unsolicited photographs of him and a certain someone, in a relationship or together. I’m not going to get into that. So that door is closed, dear reader."

Chuckling, the Thor star responds, "Thank you."

While Hiddleston isn't pressed to talk about Swift, he's quite vulnerable during the interview, even revealing his biggest fear in life is regret. "I fear looking back and wishing I had done things I hadn’t," he admits. "It’s interesting, I read this extraordinary article about a book, many years ago, by an Australian nurse who is a specialist in palliative care. It was her job to help people on their way out, to ease their pain. So she spent a lot of time with people in their last days and weeks. And she felt so moved by the accumulated experience, because she heard people say such similar things. Weirdly enough, at the top of the list was, 'I wish I hadn’t worked so hard.'"

Hiddleston also gushes over his parents, who Swift met when the two first started dating, and the childhood they provided him. "I feel so grateful to my mother and father for a happy childhood. There are things I now understand that they were able to give me that are very special," he shares. "And I think the early years, the first decade of your life, is the most formative in a way. Other than that, I’m grateful for people who have believed in me when others might not have."

The Emmy nominee is also happy to chat about his friendship with Thor co-star, Chris Hemsworth. The two are currently working on a sequel in Australia for the popular film franchise. "The best thing about it, honestly, is working with Chris again. I first met him in Kenneth Branagh’s house in England in 2009," he recalls. "We were mere children, in the very beginning of our acting journeys. We made an instant connection, and it’s been extraordinary to share the ride with him -- this mad journey with Marvel."

In addition to his interview, which was done over the phone in August, Hiddleston shows his darker side, posing in a series of leather-clad, vampire-esque outfits for a sexy photo shoot for the magazine.
