Here's a word of advice: don't ever tell Kate Winslet about your inner-most sexual fetish, because she'll go on national TV and tell everyone. Something that Idris Elba discovered the hard way.
While making an appearance on The Graham Norton Show, the actors, who appear alongside each other in The Mountain Between Us, revealed they had to strip to their underwear for the film's more intimate scenes let was essentially nude, save for her socks per Elba's request.
Which brings us to the fetish.
Can you guess what it is?
"Idris was a bit nervous too and everything was moving a bit slowly so I just said, 'Okay boys, this is what we are going to do...' and we just got on with it," the Titanic actress explained about filming with the 45-year-old and director Hany Abu-Assad. "We got naked but Idris asked me to keep my socks on. I thought he didn't like feet, but it is the opposite. Idris loves feet!"
Elba confirmed his foot fetish, stating: "I've just got a bit of a thing."
Haven't we all, Idris?.. Haven't we all? (well not us, but everyone else probably does)
