Ryan Reynolds and Olivia Wilde are spilling all their dirty little secrets!
The former "Change-Up" costars stopped by "Watch What Happens Live" on Thursday, where they were grilled about what really goes on behind the scenes of their raciest sex scenes.
Host Andy Cohen went right in on Ryan, asking if he wears a "c**k sock" to protect his goods.
"At home, always," he joked. "Yeah, I do sometimes."
"It's the polite thing to do," Wilde chimed in. "I do believe you should always wear a c--k sock, even when you're not naked," Ryan added.
The "Deadpool" star also admitted that he was only wearing "a dash of baby powder" during his nude scenes with Sandra Bullock in "The Proposal."
As for Olivia, she joked that she was "knitting" when got intimate with Ashley Greene in "Butter."
The actress also was quizzed about kissing Mischa Barton on "The O.C."
While Andy assumed Mischa tasted like "cigarettes," Wilde quickly shot that down and said, "She tasted like My Little Pony and sweetness and love."

Later in the show, Blake Lively's other half didn't hold back during a game of "Plead the Fifth."
Andy described the character, Deadpool, as a "pansexual hero" who is "very horny all the time," but then asked Ryan which superhero he thinks could be a "flaming homosexual."
"Why do they have to be on fire?" Ryan joked. "Can't they just be homosexual?"
He finally came to an answer: Archie.
Next up, Reynolds was asked to rate the movie, "The Green Lantern," from 1 to 10.
"I would give it a scant four. Three or four," he declared. "It didn't work. OK it's a one. It's a one."
