New Arnold Schwarzenegger Admissions

Arnold Schwarzenegger and a mystery blonde were out together while he insists he wants to win back estranged wife, Maria Shriver. Arnold and the mystery woman were spotted bicycling together in Pacific Palisades, California, on Sunday.

Meanwhile, Maria was photographed alone over the weekend wearing a huge ring on her wedding finger. Turns out it's an engagement ring that once belonged to her late mother Eunice Kennedy Shriver, not a sign that she is thinking of getting back together with Arnold.

INSIDE EDITION is learning that Arnold has another confession to make to somebody besides Maria.

On NBC's Meet the Press, he watched a 2003 Today show interview he did with Matt Lauer when he ran for Governor of California. Lauer asked about his tax returns. In his new autobiography, Total Recall, Arnold now said he was pretending he couldn't hear Lauer so he didn't have to answer the question.

Arnold said, "Maria was really mad about it. I remember she called me after and she said, 'You really have to go and start thinking about what you are going to say in those interviews.' I said, 'You better believe it.'"

And Arnold is also making another startling admission - that he once expressed admiration for Adolf Hitler.  

For decades, Arnold denied making the comment in an interview that was cut from his 1977 bodybuilding documentary Pumping Iron.

Now he said in his autobiography, "I admired Hitler's speaking ability, though not what he did with it."
