Kit Harington's publicist exploded rumors suggesting that the piece of Game Of Thrones betrayed his new bride Rose Leslie.
The 31-year-old singer is linked to Russian model Olga Vlasova after she posted a supposed nude photo of the online actor.
Vlasova claims he met Harington in Luxembourg and in the photo, a man who appears to be the actor can be seen sleeping in a bed.
The model also claims she became involved with Harington when he was engaged to Leslie, but the actor's agent insists the story is all invented.
"The allegations in this story are completely false," the representative said in a statement. "He (Harington) has never been to Luxembourg, nor did he meet Olga Vlasova."
Harington and Leslie, their former love interest in Game of Thrones, exchanged vows at the Kirkton of Rayne church in Aberdeenshire, Scotland, in June, in front of guests who included TV cast members Emilia Clarke, Peter Dinklage, Maisie Williams and Sophie Turner.
After the ceremony, friends and family celebrated at Leslie's family estate, Wardhill Castle.
Harington and Leslie met on the set of Game of Thrones in 2012 and got engaged last year.
Harington had already made an effort to tell his best memory about working on his fantasy drama, finding his now-wife on location in Iceland.
"The country is beautiful … the aurora borealis are magical … it was there that I fell in love," he told Lomo Uomo Vogue. "If you're already attracted to someone and then they throw your love interest in the show, it's very easy to fall in love."
