It doesn't seem like the most fun thing to do would be watching yourself have fake sex on a movie screen.
Unfortunately for Kristen Stewart, she's had to do that a couple of times after she had a fake threesome in her new movie On The Road, and it hasn't been easy.
She recently did an interview with Indiewire where she revealed that watching the sex scenes as isolated moments are "fairly ridiculous".
She told the site:
"To be honest, I think if you were to isolate the scenes, it’s fairly ridiculous watching yourself fake have sex. But within the movie, watching the movie, I do get so caught up in this one. I’ve seen it three times, and that’s not typical for me. I have to complete the process, I need to watch the movie at the end of it."
Kristen is certainly a trooper for watching those scenes three times!
