What happens when you cross a Killer Queen with Princess Diana? Romantic speculation, that's what. 

It would appear that actors Rami Malek and Emma Corrin are more than just friends. In photos published by The Daily Mail, Malek, who won an Oscar for Bohemian Rhapsody, and Corrin, who was nominated for an Emmy for their portrayal of Princess Diana on The Crown, stepped out to walk a pooch and share a smooch in London Thursday.

Corrin, 27, wore a knee-length tan trench coat and wide-legged pants, accessorizing their tightly buzzed haircut with a pair of shades. Malek, 42, wore cuffed jeans and a sweater, topped off with a royal blue ballcap. Both are also pictured at one point carrying their shoes in their hands and walking barefoot on the grass. 

The pair was spotted together at a Bruce Springsteen concert in Hyde Park in July, and have popped up around London dining together.

Malek and Bohemian Rhapsody co-star Lucy Boynton dated for about five years, and reportedly called it quits this summer.

An unnamed source told The Sun this summer that Malek and Corrin “just seemed totally besotted with each other and paid no attention to anyone else.”

Corrin was a cover star of this year’s Vanity Fair Hollywood Issue, where they said that, as a non-binary actor, they would “love to play nonbinary, new parts, male parts. Anything, as long as it’s right.”

They also spoke of the desire to keep their personal life private, while still staying authentic.

“I try to be as much myself as possible,” they said. “I think it’s finding a balance so that you’re always living and presenting yourself authentically, but also keeping as much as you can of yourself private so that you have that to hold on to—not to feel like you have to overshare yourself, which I think sometimes there’s a pressure to do. That is a total learning curve, and you don’t get it right sometimes.”

Vanity Fair reached out to representatives for both Malek and Corrin. Corrin’s team declined to comment, while Malek’s did not immediately respond.
