Even Julianne Moore gets intimidated sometimes -- and with Madonna as a costar, we don't blame her!
The "Still Alice" star appeared on "Watch What Happens Live" Wednesday night and reveled to host Andy Cohen that working with the pop-icon was super nerve wracking.
The 54-year-old and the "Like A Virgin" singer starred together in 1993's "Body of Evidence." In the film, Julianne had to slap Madonna's across the face -- and when the sweet actress was asked if she was scared to shoot that particular scene, her response was telling.
"I was super nervous. I was so so nervous," she told Cohen. "I didn't actually make contact. It was a fake slap."
As if that wasn't enough to scare the Oscar nominee, Madonna stayed in character in between scene's and completely "iced" her out.
"She wasn't talking to me, cause she was being kind of method-y doing her thing, and so I felt nervous and scared. I didn't want to hit her at all," she continued.
But the fun didn't end there! Watch the clip below to see Julianne play "Plead the Fifth" and reveal who her best on screen kiss was:
