Jon Snow knows nothing about recent cheating allegations.

"Game of Thrones" actor Kit Harington is calling claims that he was unfaithful to his wife Rose Leslie with a Russian model "completely false."

Model and "Doma-2" actress Olga Vlaslova alleges that she had an affair with Harington during his engagement to Leslie that continued into their marriage, after the pair met in Luxembourg, according to ET Canada and Russian media outlets.

Vlaslova took her claims a step further by sharing a nude image of what appears to be Harington sound asleep on a bed next to a laptop, the outlets add.

"The allegations in this story are completely false," Harington's representative, Marianna Shafran, told USA TODAY in a statement. "He’s never even been to Luxembourg, nor has he ever met Olga Vlaslova."

Harington and Leslie, both 31, met in 2012 on set of "Game of Thrones," where they played couple Jon Snow and Ygritte. Their onscreen love blossomed into a relationship outside of the HBO fantasy series.

The couple got engaged in September 2017 after Harington bent the knee and they married in Scotland in June 2018.

The actor told Vogue Italia in 2016 that filming in Iceland during the show's second season was his best memory, a month after going public with his relationship with Leslie.

"Because the country is beautiful, because the Northern Lights are magical, and because it was there that I fell in love," he shares. "If you’re already attracted to someone, and then they play your love interest in the show, (it) becomes very easy to fall in love."
