Former Gov. Arnold Schwarzenegger says the affair he had with a member of his household staff, which resulted in a child he kept secret for more than a decade, was "the stupidest thing I've done" in his relationship with Maria Shriver.
"I think it was the stupidest thing I've done in the whole relationship," Schwarzenegger says in an excerpt of a "60 Minutes" interview scheduled to air Sunday. "It was terrible. I inflicted tremendous pain on Maria and unbelievable pain on the kids."
Schwarzenegger, is promoting his new autobiography, "Total Recall: My Unbelievably True Life Story," which comes out Monday.
