Diego Luna would rather not know about Princess Leia and Han Solo’s sexual history.

The Rogue One: A Star Wars Story actor sat down for a chat with PEOPLE Now, and had a priceless reaction to Carrie Fisher’s recent admission that she and Harrison Ford had a fling on the set of Star Wars.

“I don’t know if I should know this,” Luna, 36, exclaimed. “I grew up with them, it’s like I know them so well — I don’t want to know, I don’t want to know!”

After keeping their romance a secret for 40 years, Fisher finally revealed that when she was 19, she and Ford — then a 33-year-old married father of two — had a whirlwind three-month affair while filming the original Star Wars in 1976.

“It was so intense,” the actress and author of the The Princess Diarist, 60, told PEOPLE exclusively. “It was Han and Leia during the week, and Carrie and Harrison during the weekend.”

Not only does Luna wish the affair had remained private, he also disagrees with Fisher’s claim that anything goes while filming on location. “I think we say that because we don’t want to accept that we really want to do something,” Luna said.
