In her interview with Harper's Baazar UK, the leading lady said the staged romp with her then-boy-toy was "agony."
"It had to be transcendent and otherworldly, inhuman, better sex than you can possibly ever imagine, and we were like, 'How do we live up to that?' Which sucks, because I wanted it to be so good."
Don't fret, FKA Ttwigs, we're sure this doesn't have anything to do with R-Patz' sex skills IRL!
The actress was just under a ton of pressure to make the scene perfect. It was the pinnacle moment of a wildly successful film franchise, after all.
On top of that, KStew also says she's not really a fan of sex scenes in general:
"I only hate them when they're contrived."
Hmmm. We wonder if she would feel differently if she had to shoot a scene with rumored girlfriend Alicia Cargile!
You can check out the whole interview in the May issue, which hit stands on Thursday!
