During an interview with The Guardian, the 66-year-old revealed that although he “knew from previous jobs” that getting romantically involved with a coworker was a bad idea, “Carrie and I were instantly attracted to each other.” “I remember one time – I’m sure alcohol was involved – we were talking about kissing techniques. I said: ‘Well, I think I’m a fairly good kisser. I like to let the women come to me rather than be aggressive.’ And she said: ‘What do you mean?’ Well, next thing you know we’re making out like teenagers!” he said. “We were all over each other!” he added, before seemingly revealing that there was a limit to how far their relationship went. “The one thing that drew Carrie and me back from the precipice was we kind of became aware of what we were doing and just burst out laughing. Which was unfortunate for me because the rocket launch sequence had been initiated,” he continued.

But I’m also grateful for all that she was able to give us while she was here. It has not been easy,” he said. Star Wars: The Last Jedi hits theaters Dec. 15.
