Kirstie: Totally Straight Travolta Is 'Love of My Life'

Kirstie Alley is on a roll. First she revealed a secret relationship with Patrick Swayze; now she says John Travolta was "the greatest love of my life." In an upcoming 20/20 interview with Barbara Walters, Alley also firmly denies rumors of Travolta's homosexuality, Us reports. "I know John with all my heart and soul; he's not gay," she says, speculating that the rumors began because Travolta is so famous but is "not out doing drugs" or "womanizing."

Alley and Travolta are both Scientologists and starred together in the Look Who's Talking films. Alley tells Walters she struggled with feelings for Travolta while still married to Parker Stevenson, whom she divorced in 1997. "It took everything I had inside, outside, whatever, to not run off and marry John and be with John for the rest of my life," she says. "I feel like when you marry someone, you're supposed to work hard at it and you're supposed to make it work." Alley is currently promoting a new memoir, the Hollywood Reporter notes. The 20/20 interview airs Friday. (More Kirstie Alley stories.)
