Kirstie Alley would have seduced Travolta if it wasn't for his wife!

Kirstie Alley has confessed she would have seduced John Travolta if he wasn't married to her good friend Kelly Preston.

The Hollywood actress, who co-starred with the 'Grease' star in 'Look Who's Talking', admits she's "madly in love" with Travolta and would have tried something but was stopped because of the loyalties she felt towards Kelly.

She is quoted by Britain's Express newspaper as saying: "I love John. I'm madly in love with John. His wife, Kelly, is one of my best friends, if not my best friend. If she wasn't, I would be unethical.

"I would say, 'Okay, now I'm just going to use the restroom,' and I'd trap John in the hall and go like, 'Alright now look, Johnny boy, just take me here, take me on the floor!

Don't worry about your wife in the other room!' "But because she is my friend I can't do that." Meanwhile, Kirstie, 54, also admitted that she once spent three days in bed because she felt so fat.

The star, who is currently starring in hit US show 'Fat Actress', revealed: "I once spent three days in bed because I felt that I was so fat, old and ugly and thought I was never going to work again."
