If there's one thing Dancing With the Stars' Kirstie Alley isn't, well, dancing around, it's her claim that she and Patrick Swayze developed intense feelings for each other while working on the 1985 miniseries North and South.

However, the Cheers alum tells Entertainment Tonight that at the time she thought, "Do not go down this road," as both of them were married.

"We did not have an affair," Alley insists. "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."

The 61-year-old actress adds, "After Patrick, I made a decision that I was not ever going to involve myself with anyone married."

Alley writes more about her relationship with Swayze in her new tell-all book, The Art of Men, out today.
