The 60-year-old details her three-month extramarital affair with Ford in her new book, The Princess Diarist, revealing they were more than just friends while shooting Star Wars: Episode IV - A New Hope in 1976, when she first portrayed Princess Leia and Harrison took on the role of Han Solo.

An excerpt purportedly from the upcoming release began circulating online on Tuesday (15Nov16), apparently suggesting Carrie, then 19, was left disappointed the first time she slept with her co-star.

The actress has since spoken out to dismiss the unfounded claims, telling, "Any reports claiming I said Harrison was bad in bed are utterly false. Perhaps people should read the book before they write their stories."

She has also taken to Twitter to address the reports, insisting her book makes no mention of Harrison's lovemaking skills.

"I would never talk about how someone was in any furniture - chair, bed, coffee table or otherwise," she joked.

Carrie has only fond memories of her short-lived affair, admitting it was "so intense", and adding, "It was Han and Leia during the week, and Carrie and Harrison during the weekend... I was so inexperienced, but I trusted something about him. He was kind."

The star also revealed she had called Harrison to warn him about her tell-all, but he didn't have much to say about the big reveal.

"He went, 'Lawyer!'" Carrie recalled, admitting she sent him an advanced copy of the manuscript but never heard back.

Despite his silence about the romance news, Carrie has no regrets about going public with her fling, even though it suggests Ford was unfaithful to his then-wife Mary Marquardt.

"It was 40 years ago," she said.

Harrison and Mary filed for divorce in 1979. He went on to wed Melissa Mathison in 1983, and now he's married to actress Calista Flockhart.

Carrie has only been married once - to singer Paul Simon from 1983 to 1984.

Harrison and Carrie both reprised their roles for Star Wars: The Force Awakens last year (15).
