In a revelation that will warm the hearts of tongue-tied lotharios everywhere, Welsh actress Catherine Zeta-Jones has revealed the chat up line that actor Michael Douglas used to snare her.

In an interview with US magazine Parade due out this Sunday, Zeta-Jones, routinely voted one of the world's sexiest women, relates how Douglas wooed her with the some would say cheesy line, "I want to father your children."

"Months later, we were dating, and I was already in love with him," she told the magazine.
