A batch of eagle-eyed Married At First Sight UK viewers believe they've finally cracked the question as to why Kristina looks so familiar.
The dog walker made her Channel 4 debut earlier this month in the hope of finding the man of her dreams - however, it was her resemblance to another huge-name star that immediately got viewers talking.
Kristina's entrance to the show hit headlines across the nation when producers released a teaser back in August ahead of the 2024 series.
In the controversial video, the beautiful bride was horrified on her wedding day - which would mark the day she'd meet her 'perfect match' for the first time - after he pulled a prank on her.

Kristina was paired up with 28-year-old mechanic Kieran, who thought it would be funny to pop a pair of rotting false teeth into his gob just moments before her arrival.
It's fair to say that the joke went down like a lead balloon, but since then, the pair's relationship does appear to have gone from strength to strength.
It isn't just the ins and outs of Kieran and Kristina's married life that has set tongues wagging since the series kicked off, however.

No, it's also Kristina's resemblance to another celebrity star.
While many viewers of the show admitted they've been left scratching the heads over who exactly she reminds them of, other social media users believe they've finally put their finger on it.
It turns out that many MAFS UK fans believe Kristina bares a striking resemblance to former The Only Way Is Essex beauty, Samantha 'Sam' Faiers.

"Christina reminds me of Sam Faiers - now I can’t unsee it?!" one viewer penned on social media this week.
Another claimed: "Kristina's doppelganger is Sam Faiers"
"Didn’t know Sam Faiers was on this years," joked a third, before another went on to jibe: "The loud annoying one don't half look like Sam Faiers #MAFSUK".

Another continued: "Kristina and Sam Faiers I knew she reminded me of someone."
"Kristina reminds me of Sam Faiers," a sixth admitted.
Kristina isn't the only individual that the dating show's fanbase believe they've seen before.

Last week, Nathan hit the headlines, with many viewers believing him to be the spitting image of Hollywood star Billy Zane.
One person wrote on X: "Nathan looks too much like Billy Zane in Titanic, can't unsee it."
A second person wrote: "Geez Nathan is a dead ringer for the actor Billy Zane."
A third added: "I was trying so hard to think of who Nathan looks like and when he smiled it came to me. Billy Zane!"
