(USA TODAY) Look for Arnold Schwarzenegger's public mea culpa on Sunday night.
The former California governor and bodybuilder-turned-action star is finally talking about his affair with his housekeeper -- in the name of promoting his new memoir, Total Recall: My Unbelievably True Life Story.
"I think it was the stupidest thing I've done in the whole relationship. It was terrible. I inflicted tremendous pain on Maria and unbelievable pain on the kids," Schwarzenegger tells Lesley Stahl on the 45th season premiere of 60 Minutes (CBS, Sunday, 7 p.m.).

The affair with Mildred Baena resulted in a son named Joseph, who is now 14. Schwarzenegger also writes of another affair he had while married to Maria, according to a show release.
Shriver would not comment to 60 Minutes about the interview or the book, which Schwarzenegger says she has not read.
"She knows that it's about my whole life and that I would not write a book and kind of leave out that part and make people feel like, 'Well, wait a minute. Are we just getting a book about his success stories and not talk about his failures?' ... I wanted to write a book about me."
