Tom Hiddleston avoided talking about Taylor Swift when quizzed by his friend Benedict Cumberbatch for Interview magazine.
The Thor: Ragnarok star took part in a Q&A with his good pal Benedict for the publication and although he discussed everything from his return to the Marvel Cinematic Universe to his work with UNICEF to his exercise routine, the Sherlock actor let Tom off the hook when it came to discussing his ex-girlfriend.
Benedict - who is married to theatre and opera director Sophie Hunter with whom he has a son, Christopher - assured Tom that he would not interrogate him about Taylor, who he split from in September.
Benedict, 40, said: "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. And, without getting into a huge debate, 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."
Prompting Tom to reply "Thank you."
Benedict then added: "You're welcome. I know you'd do the same for me."
Since the end of their three-month romance, Tom has spoken about the Shake It Off hitmaker only to insist they are on good terms despite the break-up.
Meanwhile, Tom admitted he lives a "boring life".
The 35-year-old actor simply goes home, reads books he hasn't had time to get through and "potters about" when he has finished filming a movie or a TV show.
When asked what he does to relax after a film has wrapped, he said: "I just go home. It's that literal and metaphorical. To London. When I finished The Night Manager, I realised that, for 75 days, I had lived more hours per day as Jonathan Pine than I had spent as myself.
"You're putting yourself into this other person's shoes. The best thing I could have done was exactly what I did.
"I flew home and I went to my sister's engagement party. I was surrounded by family. And they were so reassuring. And then I just, I live such a boring life. I just potter about, read books I've meant to read but haven't had time."
But when Tom - who starred as spy Jonathan Pine in TV thriller The Night Manager - is on a movie or TV set he loves to get up early and go for a run in the morning because he can clear his head and often has his "best ideas" at that time.
Quizzed by his friend Benedict Cumberbatch for Interview magazine, he added: "You've got to do something, even if it's just to kick-start the day. I use music. And running.
"I find that, when I'm working, if I start the day with a run - outside, not in a gym, but just me out there in the elements, with only my own legs to propel me forward ... It's something to do with just being in the world and getting out of my own head.
"You have to be [disciplined to get up early]. You can't function. And it varies from job to job.
"On Kong: Skull Island, we were always outside. My character was a former SAS tracker, so he's sort of an ultimate athlete - I would always be able to just, like, run around and get my blood up if I was feeling sluggish."
