Arnold Schwarzenegger and Maria Shriver are terminating their marriage after 25 years together. The couple announced their separation in a joint statement on Monday.

"This has been a time of great personal and professional transition for each of us," the statement read. "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."

"We are continuing to parent our four children together. They are the light and the center of both of our lives. 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."

The couple is experiencing major life changes: Arnold left the office of California governor and has been making his way back into Hollywood, while Maria has suffered through the deaths of both parents, her beloved uncle, Ted Kennedy, and several close friends while continuing her philanthropic work.

Maria hinted at the major changes in her life in this YouTube video posted March 28 where she asks viewers how they handled transitions:
