What EXACTLY happened between Kirstie Alley and Patrick Swayze in 1985 then? Little did we know that the North & South co-stars had a secret affair all those years ago but Kirstie made the shocking revelation to Entertainment Tonight, in an interview that will air this evening (November 6, 2012). Both Kirstie and Patrick were married at the time that she claims they fell in love but she stops short of labelling their dalliance as an ‘affair.’

Alley claims that as they were both married, they tried to stop things from “going down that road” but she admits that they couldn’t help it, in the end. “Both of us were married,” she told Entertainment Tonight and added “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.”

At the time of their attraction, Kirstie was married to her second husband, Parker Stevenson and Patrick was married to Lisa Niemi – with whom Alley is still good friends… for now, at least. The actress insists that she and Lisa are good pals but sys that she’s unsure if Lisa was already aware that she and Patrick had such strong feelings for each other, when she asked Alley to speak at Patrick’s funeral.
