The Los Angeles Times reported Tuesday that the former California governor admitted to Shriver that he'd fathered a child with their housekeeper.
Schwarzenegger's admission to fathering a child resulted in his separation from Shriver, according to the Los Angeles Times.
"After leaving the governor's office, I told my wife about this event, which occurred over a decade ago," Schwarzenegger said in a statement. "I understand and deserve the feelings of anger and disappointment among my friends and family. There are no excuses and I take full responsibility for the hurt I have caused. I have apologized to Maria, my children and my family. I am truly sorry."
There were not only allegations of Schwarzenegger's cheating, but women also came forward saying that the movie star groped them. There were even tabloid reports of a love child.
During an interview with ABC News' Peter Jennings at the height of the 2003 recall campaign Schwarzenegger denied them all.
"Isn't it odd that three days and four days before the campaign, all of sudden all these women want to have an apology? Isn't it odd?" Schwarzenegger asked. "I mean, you have common sense … You can figure this out for yourself."
Speaking with Winfrey about the allegations against her husband in 2003, Shriver vigorously defended the man she loved.
"I am my own woman. I have not been quote, "bred" to look the other way. I look at that man back there in the green room straight on, eyes wide open, and I look at him with an open heart."
Only now is it completely clear just how badly Shiver was betrayed by her husband.
