Former "Game of Thrones" star Leslie Rose crushes on Idris Elba after they finished shooting new episodes for season 4 of "Luther."

Is she replacing Kit Harington in her life?

"Watching Idris Elba on set and seeing his effortless skill in front of the camera..." she told In Style, per Daily Mail.

"It wasn't verbal, and I sound incredibly pervy right now, but the way he operates on and off camera is something I'll take with me," she said.

Back in September, it was reported that Leslie Rose and Kit Harington are back together after splitting earlier this year.

In an Instagram post by user The Kyrbin, it did appear that Jon Snow and Rose Leslie are back together as they seemed to be cozying up while on an escalator. The caption read, "You know nothing Jon Snow. Yes, it's the Wildling and Jon Snow. Yes, they were holding hands #wow #gameofthrones #kirbyn."

One fan wrote, "My heart just broke a little but then again, they're a cute couple."

In January this year, Kit Harington talked to GQ magazine where he admitted that he has no ladylove at the moment.

"I'll never talk about any particular relationship I've been in," he said. "But I will say I'm single at the moment."

The "Game of Thrones" star went on to add, "Relationships as an actor are incredibly difficult. With someone who's not an actor, because they never get to see you; and with someone who is an actor, because you're ships in the night a lot of the time. I mean, ideally, if you keep acting in the film world, you're a travelling salesman."

The on-and-off couple got back together in May last year after splitting the year prior. Kit Harington and Rose Leslie reportedly knew each other even before playing on-screen lovers in "Game of Thrones."

Idris Elba, meanwhile, is still very much with girlfriend Naiyana Garth where he has a son. He also has another daughter with previous wife, Kim.
