Carrie Fisher reveals "intense" affair with Harrison Ford on set of Star Wars

Fisher is going public with the secret she has kept under wraps for 40 years, in her new memoir The Princess Diarist, opening up about the three-month-long affair with the then-married father of two.

“It was so intense,” Fisher told People magazine. “It was Han and Leia during the week, and Carrie and Harrison during the weekend."

At the time, Fisher was just 19, while Ford was 33 and married to first wife Mary Marquardt. He reportedly had a heads-up about the book, and was send a draft copy.

After rediscovering the journals she kept while filming on location in London, Fisher decided to share her experience and her memories.

She details how she felt after they spent their first night together following a birthday party for director George Lucas.

“I looked over at Harrison. A hero’s face — a few strands of hair fell over his noble, slightly furrowed brow,” she writes. “How could you ask such a shining specimen of a man to be satisfied with the likes of me?”

She adds: “I was so inexperienced, but I trusted something about him. He was kind."

As for reports that the autobiography will reveal how Ford was in bed? Not likely, says Fisher.
