Kirstie Alley stopped by Jimmy Kimmel Live Thursday, Nov. 8, to discuss her new book, The Art of Men -- and to set the record straight about a few things involving her past relationships with Travolta and Swayze, both of which went on while she was married to Parker Stevenson. (They split up in 1997, after 14 years of marriage.)
"Can I just clarify, these were not sexual affairs," Alley, 61, explained to Kimmel. "I think John Travolta is and has remained one of my best friends for almost 25 years, 26 years . . . before he was married [to Kelly Preston], and I was married. But I fell in love with him."
Alley went on to say that her romantic feelings for Travolta (her costar in 1989's Look Who's Talking) "evolved" into "the most brilliant friendship," and that she's now just as close with his wife of two decades as she is with the actor.
When asked by Kimmel if her feelings for Travolta were unrequited, the Cheers alum replied that it was "even steven" between them.
"And you know that's not a good thing to do. The only good part of it is I didn't turn it into a sexual relationship, which is really good," Alley shared, confessing that she has a tendency to get attached to the men she sleeps with. "Because for me, if I have sex with someone, I have to marry them."
Plus, "My mother told me I would be a whore if I didn't marry someone I had sex with, so I was trying not to be a whore."
As for Swayze, who passed away in 2009, Alley revealed that she's "proud" that they were never physically intimate.
"Once you have sex with somebody else -- I thank God I'm not that girl," she shared.
Alley also revealed that -- throughout the course of both of her emotional affairs -- she tried to be as honest as possible with Stevenson about her feelings for her costars, confessing that while filming intimate scenes together, "it's a little hard to confuse the boundaries."
