Former actor and California governor Arnold Schwarzenegger and his wife Maria Shriver announced on Monday that they are getting divorced, after 25 years of their marriage.

In a joint statement, the couple said, “This has been a time of great personal and professional transition for each of us. After a great deal of thought, reflection, discussion, and prayer, we came to this decision together. At this time, we are living apart, while we work on the future of our relationship.”

The shocking statement came four months after Schwarzenegger, the Hollywood action star had finished a seven-year run as California governor in January.

We are continuing to parent our four children together. They are the light and the center of both of our lives, they said in the statement. We consider this a private matter, and neither we nor any of our friends or family will have further comment. We ask for compassion and respect from the media and the public.

Shriver who was an author and journalist for NBC, had left her job when Schwarzenegger took office as governor of California. She is an active member with many voluntary organizations.

Shriver was daughter of the late Eunice Kennedy Shriver, who was the sister of assassinated U.S. President John F. Kennedy. Her father Sargent Shriver was the Democratic candidate for vice president in 1972.

Though a lifelong Democrat, Shriver campaigned for her Republican husband when he sought to recall and replace then-Governor Gray Davis, a Democrat, in 2003 and She took to the stump to help Schwarzenegger win re-election in 2006.

However, she never joined Schwarzenegger in Sacramento when he was governor and preferred to stay in their estate with children. Schwarzenegger was often flying home by his private jet.
