Anya Taylor-Joy and her husband were "pretty spy-orientated" when they planned their secret wedding

She told 'Entertainment Tonight': "We did our research, we were like pretty spy-orientated. But honestly, it just -- it kind of made it all the more special 'cause it just felt like a secret that we got to keep to ourselves."

The 27-year-old actress had a "magical" wedding day, with her and Malcolm exchanging vows just in front of their "two best friends", but they were happy to celebrate their union with wider friends and family at a later date.

She said: "At the end of the day, it was about the two of us and so we ran away with our two best friends and had the most magical day possible.

"But I was also very grateful that a couple of months later we were able to celebrate with our family."

Anya revealed her secret nuptials in an Instagram post celebrating her second wedding anniversary with the 29-year-old musician on 2 April.

She wrote: "Two years ago, on April Fools, I secretly married my best friend in New Orleans. The magic of that day is ingrained in every cell of my being, forever.

"Happy second ( first ) anniversary my love...you're the coolest."

The Golden Globe-winning star shared her message alongside a series of images from the big day and revealed through her photo credit that Cara Delevingne had been present at the nuptials.

Commenting on a snap of her heart cakes, she concluded her post by writing: "N.B yes, those are anatomically correct heart cakes. Yes, I am the vampire Lestat. [camera emoji] @caradelevingne + @sebastianfaena, beautifully embroidered with our love story by @dior."

Malcolm also shared his own tribute on social media after the announcement was made.

He wrote: "I love you now and somehow I always have and somehow it will never end Happy two year anniversary (yesterday), beautiful."

It had previously been reported that the couple had said their vows in a lavish ceremony in Venice, Italy and photos from that time show the 'Dune: Part Two' actress in the same Dior gown shared in her social media post but she had always referred to her husband as her "partner" until now.
