A look inside Elizabeth Debicki's deeply personal relationship with mystery man Kristian Rasmussen – it's revealed he sneaks into awards shows to support her

Elizabeth Debicki is no stranger to the spotlight after receiving numerous awards for her portrayal of Princess Diana in the Netflix series The Crown.

Despite often turning heads on the red carpet, the Hollywood star, 33, has managed to keep her love life incredibly private.

Little is known about her mystery man Kristian Rasmussen, with whom she was first spotted holding hands in London in November 2022 by Daily Mail Australia.

But while the award-winning actress keeps her love out of the spotlight by walking the red carpet alone, it seems Kristian doesn't shy away from sneaking into prestigious events to support her.

Elizabeth's rarely seen boyfriend – who bears a curious resemblance to The Crown's former Prince Phillip Matt Smith – reportedly sneaks into awards shows to cheer her on from the audience.

In an attempt to avoid cameras and reporters, he flies under the radar as his glamorous girlfriend poses on the red carpet and takes the stage to accept her awards.

The happy couple were last seen wandering the streets of London in February last year, not long after attending the SAG Awards together.

As Elizabeth walked the red carpet as usual, she hinted that Kristian was in the crowd during her acceptance speech for Best Supporting Actress.

'Thank you so much. Thank you to the creatives of this show for trusting me in this role, to our cast and crew, to my beautiful fantasy children, to my mother and my father and Kush and Tommy who are in Australia hoping they are in their pajamas I look at this,” she began.

'My partner Kristian who said: don't thank me so I don't appear on television, but I'm going to thank you anyway. Who else? Thank God, maybe that's it… this is just amazing to me!'

Just a few months earlier, Elizabeth was joined by her very own Prince Charming as she celebrated the launch of series five of Netflix drama The Crown in November 2022.

Weeks after they were first spotted together, the talented star was spotted leaving the red carpet premiere at London's Theater Royal Drury Lane with Kristian.

The couple made their first red carpet appearance and their second in as many days, after heading out hand-in-hand the day before.

Dressed in an elegant black evening gown, Elizabeth climbed into the back of a waiting taxi with her boyfriend after attending an after-show party.

Kristian looked suitably dapper in a black tuxedo and matching shirt as he followed her to the backseat.

The previous day they were seen holding hands during a shopping trip in London, with Elizabeth laughing with her new boyfriend as they enjoyed a hug and a kiss.

In February last year, the lovebirds put on a fun performance as they stepped out into London again, bundled up against the cold for a romantic stroll.

Despite rising through the ranks of Hollywood for her starring role in The Crown, which earned her Astra, Critics Choice and Golden Globe awards, Elizabeth has successfully kept her love life with Kristian private.

Elizabeth often takes to the red carpet in glamorous looks when she attends events, but that doesn't mean she comes alone as Kristian often manages to sneak in.

In 2018, the rising star, who first burst onto the scene in 2014 for her award-winning role in The Great Gatsby, told Vogue Australia about her desire to remain private.

'I've always been a private person. “I feel like what I want in the world is my work and I've always believed – and it's the way I approach my work – that me and the work are separate,” she said.

'I think with social media people can blur it so beautifully, and I respect that, but it's not really who I am and I just want the work to speak and for people to receive it the way they want without anything influencing it has finished.'

She ended by saying, “I just want people to know me for my work.”
