Michael Douglass thought he ''totally blew'' his chances with Catherine Zeta-Jones after their first date.

The 72-year-old actor - who has been married to the 47-year-old actress for 16 years and have daughter Carys, 13, and son Dylan, 16, together - has revealed he believed his cringe-worthy chat up line, which saw him tell the brunette beauty he was going to be the father of her children, had scared away his spouse.

Speaking about the couple's first date and the fateful one liner on 'The Jonathan Ross Show', which will air on Saturday (05.11.16), the movie legend said: ''[He said to Catherine] 'You know, I'm going to be the father of your children.'''

However, the 'Mask of Zorro' star didn't seem impressed and after revealing to Michael at the time she knew ''a lot'' about him and his past, she swiftly left.

Speaking about his partner's response, Michael - who has a 37-year-old son, Cameron, from his previous relationship with Diandra Luker - said: ''[Catherine said] 'I've heard a lot about you and I've seen a lot about you and I think it's time that I said goodnight.'

''So I thought 'I've totally blew it.' She was gone early the next morning and she went to [Scotland]. I thought 'It's all gone I've just destroyed it.'''

However, the 'Fatal Attraction' star admitted he tried to make it up to Catherine by sending her a bouquet of roses and an apology note.

Meanwhile, the silver fox has credited his wife for keeping him looking ''sexy'', although he feels like a pre-historic being because he can't get to grips with social media.

Speaking previously about the secret behind looking youthful, he said: ''I'm popping along, a healthy, decent-looking 72. What's the secret to staying sexy at 70? Like your wife and like your work.

''I'm a dinosaur. Thank God for Catherine - one of the huge benefits of having a young, beautiful wife is that she's also very aware of social media and how you get from here to here.''
