Who's better at car sex, Julianne Moore or Juliette Binoche? Someone asked.
"They're both sevens," he joked.
"Obviously Julianne," who was sitting next to him on the panel.
"It was a wonderful experience. Extremely sweaty."
So, how does that stack up to scenes with then girlfriend Kristen Stewart?
He has previously admitted that he found those scenes with KStew embarrassing saying, "I think the more comfortable you are with each other, the harder it gets to do any kind of really intense relationship scene.
You're kind of thinking, 'I don't want to embarrass myself in front of this person,' 'I know what she's thinking now,' so it becomes ridiculous after awhile."
This should be his last movie for a little while as he focuses on his music.
We're still wondering if any Kristen Stewart heartbreak songs will appear on the debut album!
