Despite the affair, Schwarzenegger - who has Katherine, 33, and Christina, 31, Patrick, 30, and Christopher, 26 with Maria - said he originally had no idea Joseph, 26, was his son.
He said: “In the beginning, I really didn’t know. And the older he got, the more it became clear to me. And, then it was just really a matter of: how do I keep this quiet? How do you keep this a secret?”
Despite the upheaval, Schwarzenegger - who has recently written a self-help book, Be Useful: Seven Rules for Life - and Joseph are now very close, and he and Maria “have a really great relationship”.
He said: “Any kind of special day we have together as a family, and everyone is really happy about that. But it’s not what it was, when we were all together under one roof as a family.
”I hate to do anything by myself. I like to travel with a bunch of people and show off. I’ve always trained with training partners, very rarely alone. When I have lunch or dinner or breakfast, I go with somebody. When I go to the football game, I go with somebody.
”I had three open-heart surgeries. Every time you go under, you don’t know if you’re going to see this world again. That makes you think about things. And then eventually, you get to an age where friends are passing away.”
