'Game of Thrones' star Emilia Clarke causes frenzy with Broadway nude scene

“Game of Thrones” beauty Emilia Clarke whipped theater fans into a photo frenzy Monday when she stepped, naked into a bubble bath during her “Breakfast at Tiffany’s” debut on the Great White Way.

Hoping to capture the image of the ravishing actress in her birthday suit, folks at the Cort Theatre audience ignored Broadway’s stringent “no photos” rule and frantically snapped shots on their cell phones, sources told The Post.

Things got so out of control that management at the West 48th Street theater has now beefed up security to keep the audience from sneaking further shots at the show, which started previews this week and opens March 20.

The bath scene occurs after Clarke — who plays lead Holly Golightly in a new adaptation of Truman Capote’s novel — brings Smith home to her apartment to recuperate after he’s injured riding horses in Central Park.

“She undresses him and he gets in the tub,” a source said. “She then goes offstage and comes back in a towel. She takes it off and gets in with him.

“So you don’t see everything. There are bubbles strategically placed.”

Photos taken at the show don’t appear to have made it to social-media sites yet, but one fan did tweet: “I would drink Emilia Clarke’s bath water.”

A rep for the show declined comment.
