"Dancing with the Stars" competitor Kristie Alley revealed that she and actor Patrick Swayze had a relationship while filming their 1985 television miniseries "North and South," even though both actors were married at the time.  

Alley told "Entertainment Tonight's" Chris Jacobs on Monday that though they did not technically have an affair, they did in fact fall in love with each other.

"We were creating a future together," she told "ET." "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." 

Ally was on "ET" discussing topics from her new book "The Art of Men," when attention turned to the late "Dirty Dancing" actor, who died in 2009. 

Yahoo reported that the 61-year-old and former "Cheers" star also said she is still friend's with Swayze's widow, Lisa Niemi, but that she does not know if Niemi ever knew about her relationship with Swayze.

Only a day after her "ET" interview, Alley took to Twitter to clarify that her "story" with Swayze "did NOT include SEX."

Swayze was known for his roles in films such as "Ghost" and "Dirty Dancing." He died at the age of 57 after losing a year-long battle with pancreatic cancer. Niemi asked Alley to speak at Swayze's funeral. When Alley met him on the set of "North and South," she was still married to her second husband Parker Stevenson, whom she divorced in 1997.

Alley is currently competing on the reality dance competition "Dancing with the Stars: All-Stars" with her partner, and professional dancer, Maksim Chmerkovskiy. 

In her most recent Barbara Walters interview, Alley told the host that John Travolta was "the greatest love of my life," and that she had to fight off the urge to "run off and marry John." The two worked together on 1989's "Look Who's Talking."
