Sir Michael Caine takes his wife with him "everywhere" - so he isn't tempted by "beautiful actresses".
The 85-year-old actor's significant other Shakira - who he has been married to since 1973 - accompanies him around the world to avoid the couple effectively leading "separate lives" by being apart.
Michael - who has daughter Natasha, 45, with the 71-year-old actress - is quoted by MailOnline as saying: "For a start, the obvious thing on location is you're going on location, you're married, with a load of beautiful actresses. You know what's going to happen.
"When you go away for a long time ... you visit places the other one's never seen, you eat in restaurants the other one's never been, you meet people the other one's never met. Both of you have started a separate life and it's very important you don't do that I think. So my wife goes with me everywhere."
Michael - who also has daughter, Dominique, 62, with his late first wife Patricia Haines, who died in 1977 aged 45 - previously admitted he was "so happy" with life he didn't know anyone who enjoyed their time on Earth as much as him.
