Don't try to get between Kit Harington and Rose Leslie.

The 31-year-old actor's rep shut down claims the Game of Thrones actor cheated on his now-wife during their engagement. Rumors began swirling after Russian model Olga Vlaslova posted an alleged nude photo of Harington online. The photo showed a man sleeping on a bed next to a laptop.

Vlaslova claimed to have met Harington in Luxembourg. She alleged that the two hooked up for the first time during his engagement to Leslie, 31, and continued their affair after his June 2018 wedding.

Harington's rep issued a statement to ET Canada, calling Vlaslova's allegations untrue.

"The allegations in this story are completely false," the statement read. "[Kit] has never even been to Luxembourg nor has he ever met Olga Vlaslova."

Harington and Leslie met on the set of HBO's Game of Thrones in 2012. She was cast as his character, Jon Snow's, love interest in the show. The pair were romantically linked for years, but didn't go public about their relationship until 2016.

They announced their engagement in September 2017 and tied the knot this past June. A number of their Game of Thrones co-stars, including Sophie Turner, Maisie Williams, Peter Dinklage and Emilia Clarke, who plays Harington's current love interest on the show, were in attendance. Harington and Leslie married in Scotland.
