Kirstie Alley admits she developed strong feelings Woody Harrelson while filming sitcom Cheers.

The actress, now 61, had to remind herself she was married to stop the temptation to embark on a passionate affair with Woody Harrelson.

Writing in her memoir, The Art of Men, Kirstie Alley revealed: “He would incessantly insist we sleep together, half joking and half serious.

“We’re not sleeping together, I would say, half wishing I wasn’t married so we could.”

When Kirstie Alley played bar manager Rebecca Howe in Cheers she was married to her second husband, actor Parker Stevenson.

The couple – who have two adopted children together, William True and Lillie Price – eventually divorced in 1997.

Woody Harrelson was not married when he portrayed naive barman Woody Boyd in the bar based comedy series from 1985 to 1993.

Last week, Kirstie Alley admitted John Travolta had been the love of her life.

The actress fell for the actor on the set of their film Look Who’s Talking, which was shot almost 25 years ago, but she couldn’t act on her feelings because she was married to Parker Stevenson at the time.

Kirstie Alley said: “Believe me, it took everything that I had, inside, outside, whatever, to not run off and marry John. And be with John for the rest of my life. [He was the] greatest love of my life.”

This week Kirstie Alley has also claimed she and the late Patrick Swayze, her North and South co-star, were once “in love”.

She told Entertainment Tonight on Monday: “Both of us were married. We did not have an affair. But again, I think what I did was worse. Because I think when you fall in love with someone when you’re married you jeopardize your own marriage and their marriage. It’s doubly bad.”

Kristie Alley insisted she is good friends with Patrick Swayze’s wife of 34 years Lisa Niemi Swayze and was even asked to speak at his funeral after he died of pancreatic cancer in 2009.

Kirstie Alley’s book The Art of Men lifts the lid on the behavior of all the guys she has dated and the famous men she has worked with.
