Kirstie Alley alleges secret romance with the late Patrick Swayze

Kirstie Alley says John Travolta wasn’t the only man she had a secret relationship with.

The “Dancing with the Stars” contestant, 61, has revealed that she and the late Patrick Swayze fell in love on the set of their 1985 TV series, “North and South.” Though they were both married at the time — Alley was still with her second husband, Parker Stevenson, whom she divorced in 1997 and Swayze was with Lisa Niemi — the co-stars developed intense feelings for each other, Alley says.

“Both of us were married,” Alley tells “Entertainment Tonight,” clarifying that they “did not have an affair.”

“But again, I think what I did was worse,” she added. “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.”
