Maria Shriver Remains Mum as Arnold Schwarzenegger Continues His TMI Book Tour

Former first lady of California keeps to herself while leaving a hair salon in Beverly Hills

Maria Shriver took time out for a little pampering on Tuesday.

And who can blame her, seeing how Arnold Schwarzenegger has been so vocal lately about the collapse of their marriage while out promoting his new autobiography,Total Recall: My Unbelievably True Life Story?

Not surprising, Shriver kept to herself as she made her way out of a Beverly Hills hair salon yesterday.

Meanwhile, Schwarzenegger continues to make appearances in support of his book.

Last Sunday, he was seen on 60 Minutes, where he expressed hope that he might one day reconcile with Shriver. He also visited both CBS This Morning and The Daily Show With Jon Stewart on Monday and appeared on Piers Morgan Tonight on Tuesday.
