His former Look Who's Talking co-star spilled the beans on her unrequited passions for the beleaguered actor to Barbara Walters on Friday's episode of 20/20, where she revealed that although they were close to hooking up, they resisted the urge because she was married at the time to actor Parker Stevenson.
"It took all the power I had" not to run off with him when they shot the comedy together in 1989, the 61-year-old Dancing With The Stars contestant confessed.
Twice-divorced Alley fought off the dynamic attraction with the man she calls "the love of my life" for two more sequels in the Look Who's Talking series, meanwhile Travolta married Kelly Preston and the couple went on to have three children together.
Despite never sealing the deal in the bedroom, the pair has remained close friends thanks to their mutual devotion to Scientology.
The full interview with Kirstie Alley airs on ABC's 20/20 at 10 p.m. Friday.
