Before she died, Carrie Fisher didn't leave too many secrets behind, but there was one she did keep.

In an interview with The Guardian, Star Wars' very own Luke Skywalker (Mark Hamill) admits that the two "got it on" during the first film in the series.

He said, "Are you kidding me? We were all over each other!”

Hamill and Fisher portrayed Luke Skywalker and Princess Leia in filmmaker George Lucas' Star Wars movies.

In the 1977 original film, the duo shared an infamous kiss before it would turn out the characters were actually brother and sister.

However it didn't last.

"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," he explains. "Which was unfortunate for me because the rocket launch sequence had been initiated."

One day they were discussing "kissing techniques" and the next they were "making out like teenagers."

“Carrie and I were attracted to one another, but I knew from previous jobs that it would have been a bad idea [to get involved with someone on set]," Hamill explains.

In addition to Hamill's confession, he also recalls about when he discovered the then 33-year-old Harrison Ford and 19-year-old Fisher were having an affair.

“Marcia [Lucas, Star Wars’ editor and George Lucas’s then wife] told me after we finished filming," Hamill reminisces. "I’m glad I didn’t know before, as it probably really would have affected me. By the time I found out, I just thought it was hilarious. But you know men – even if we don’t want to have a relationship, it’s just in our nature to jockey for affection."

Hamill however doesn't seem to have many regrets: he's been happily married for 40 years with three kids, and he and Fisher remained lifelong friends.
