Arnold Schwarzenegger and Maria Shriver Separate

After 25 years of marriage, Arnold Schwarzenegger and Maria Shriver have announced they are separating. “This has been a time of great personal and professional transition for each of us,” the couple said in a statement. “After a great deal of thought, reflection, discussion, and prayer, we came to this decision together.”

The ex-California governor and once-and-perhaps-future Terminator star has been traveling solo since he left office. The Los Angeles Times notes he has been to “Brazil’s Xingu River with director James Cameron, to London for Mikhail Gorbachev’s 80th birthday party, to Val d’Isère in France for skiing and to Washington, D.C., to attend a White House summit on immigration.”

Maria Shriver, whose marriage to Schwarzenegger united the Kennedy dynasty with Hollywood royalty, has been working on her women’s empowerment website.

One modern-day sign of their marital woes: The couple didn’t say anything about their April 26 25th wedding anniversary on their respective Twitter feeds.

The New York Times notes Schwarzenegger “might never have been elected were it not for his wife,” who defended him from accusations that he was a serial groper and womanizer. Shriver, who resigned from NBC News when her husband became governor, has reportedly moved out of their Brentwood mansion.
