Natalie Dormer is on the "Elementary" set!

The British actress, who plays Margaery Tyrell on "Game of Thrones," has joined the CBS drama's take on the classic Sherlock Holmes stories as the revered Irene Adler. TV Guide was the first to report the casting news earlier this week.

Jonny Lee Miller, who plays Sherlock in the show, tweeted a picture of himself with Dormer on the "Elementary" set.

Adler has been an unseen character on "Elementary" Season 1. She was described as Sherlock's ex who died at the hands of serial killer "M.", which fueled Sherlock's descent into drug addiction. When Sherlock later confronted "M." -- who turned out to be Sebastian Moran (Vinnie Jones) -- he learned that Adler was actually killed by Moraiarty.

In November, "Elementary" executive producer Rob Doherty told TV Guide, "As we build our Irene and we get into more detail, obviously, she has to be fairly unique, in that someone like Sherlock found himself attracted to her ... As we've said in the past, he doesn't really like to get close to anyone, let alone women. The way we've depicted him, to this point in the season, he's not an especially romantic kind of guy ... Irene has to have a certain strength. I see someone who has to have managed to surprise Sherlock in small, but significant ways. He's so easily bored by the predictable."

Following "Made in Jersey's" demise, Doherty told TV Guide that the late CBS legal drama's star Janet Montgomery could play Adler.

And in January, at the 2013 Television Critics Association's Winter Press Tour, Doherty told reporters (via The Hollywood Reporter) that viewers "will see a living, breathing actress reading lines and portraying Irene," but hinted that that could be in flashback form.

Irene Adler has frequently been used as a romantic interest for Holmes in adaptions of Sir Arthur Conan Doyle's original work. In the film franchise starring Robert Downey Jr., Rachel McAdams plays Irene Adler and in BBC's "Sherlock," Adler was portrayed by Lara Pulver opposite Benedict Cumberbatch.

Do you think Natalie Dormer will make a good Irene Adler on "Elementary"? Do you think Janet Montgomery should've gotten the part? Sound off in the comments!

"Elementary" airs Thursdays at 10 p.m. ET on CBS.
