Princess Leia and Han Solo were creating Kylo Ren right in front of Luke Skywalker, and he had no clue.

Carrie Fisher recently revealed that she and Harrison Ford had an "intense" affair in 1976, during filming for the original "Star Wars" movie, Episode IV. Fisher waited 40 years to share the news -- which she printed in her new book -- and apparently Mark Hamill had no idea his co-stars were ever an item. Considering his character was hot for his own twin sister, maybe it's not a shock that he was clueless.

"I was so self-involved at that point, they could've been doing it in front of me and I wouldn't have noticed," Mark Hamill, now 65, joked to Entertainment Tonight, adding that he "was blissfully unaware" of the affair. "I think it might have been a distraction if I'd known what was going on." Thankfully, he said, "I was single and had my own agenda."Hamill went on to say on-set flings are pretty "commonplace" but "tricky" and he had his own "awkward" issue with one when acting on "General Hospital." Ironically, it was with a co-star who played his sister. (He should be in therapy for sister issues.) .

So Luke can be relied on to save the galaxy, but the Force is not strong with him when it comes to romance. Duly noted.
