'I'm To Blame For It': Arnold Schwarzenegger Takes Responsibility For Breakup From Maria Shriver

Arnold Schwarzenegger appeared on Howard Stern's radio show on Wednesday and got candid about many subjects, including his split from Maria Shriver, his love child Joseph Baena with his former housekeeper Mildred Baena. He also talked about his son Patrick -- and Patrick's former girllfriend, Miley Cyrus.

Schwarzenegger said his breakup from Shriver was his biggest failure in life -- and he took full responsibility about it. "Without any doubt. Not only failure, but you feel like, 'I'm to blame for it. It was me that screwed up',” Schwarzenegger told Stern.

The former Republican governor of California had come to promote his upcoming movie “Terminator Genisys.” The actor said he cannot blame anyone else for the failures in his personal life. “But it's always easy to be smart in hindsight. The thing was, how do you make the best of that situation?,” the 67-year-old said.

He also talked about how he did not like going to marriage counseling to save his marriage. For Schwarzenegger, the counselor talked “more crap and more nonsense,” which was “counterproductive” to his relationship with Shriver. He apologized to Shriver and his four kids: Katherine, 25; Christina, 23; Patrick, 21; and Christopher, 17.

He also talked about his fifth child, Baena, who is now 17. "He's terrific and he totally understands the situation. So, it all has worked out,” said the actor, admitting that the birth of Baena, as the result of an affair with his and Shriver's former housekeeper, was a “very tough situation” for him and everyone in his family. “But it has happened and now we have to figure it out, right?"

The actor also discussed his son Patrick's relationship with Cyrus. The actor was not worried about his son dating the singer because to him Cyrus was a “wonderful and fantastic person.” He also met Cyrus during one of his family's holidays and said that she brought gifts for all the kids in his family and spent a lot of time with them. “I think Patrick had a wonderful experience, he had a great relationship and then the whole thing eventually fell apart," he concluded.
