Carrie Fisher, Star Wars' Princess Leia, has been keeping a secret for almost 40 years and now she finally reveals: she and Harrison Ford had a three-month affair while Ford, then 33 years old, was married and fathered two children. This was in 1976, the year Star Wars: A New Hope was filmed, and Fisher was then 19 years old.

Fisher sums up the affair to this, "It was Han and Leia during the week, and Carrie and Harrison during the weekend."

The world was caught by storm when she revealed the secret on her self-authored book, The Princess Diarist.

Some netizens were totally caught off the hook, while others seemed not to be surprised at all:

"Carrie Fisher had intense affair with Harrison Ford!!! Now I'll never get that out of my head when watching Star Wars," a Twitter user says. Another retorts, "Everything about this is pure Ford and Fisher and I love it... (and) I refuse to accept that Hot Young Harrison Ford is bad in bed."

Now 60 years old, Fisher came upon the idea of revealing the secret when she came across her journals that she regularly updated while then filming in London. She says that her journals were filled with feelings of anger and humiliation, and she felt the time is right to come out as she learned a lot from the experience.  

"It was so intense," Fisher says, referring to the affair. And she still remembers fondly the first night they spent together, which was after a party they both attended for Star Wars creator George Lucas' birthday.

Fisher continues, "I looked over at Harrison. A hero's face... How could you ask such a shining specimen of a man to be satisfied with the likes of me?" Her 19-year old self was then filled with doubts.

True enough, after the filming of Star Wars: A New Hope, the first in the movie series, the affair reached its end.

Although Fisher says she was inexperienced, she trusted Ford. And this is why almost 40 years on, she still has fond and vivid memories of the three-month whirlwind affair.

Back in 1976, at the time of the affair, Ford was married to Mary Marquardt with whom he has two children. They divorced three years later. Then in 1983 he married E.T.: The Extra Terrestrial screenwriter Melissa Mathison, and the couple divorced in 2004. Ford is currently with Calista Flockhart whom he's been married with since 2010.

Fisher has been married to musician Paul Simon from 1977 to 1983, and never remarried.
