Schwarzenegger is an active member of Twitter. Since November, when Jerry Brown won the election that made him Schwarzenegger's successor as governor, the former movie star has mentioned his wife three times. One tweet was about getting together with the Browns to talk about the transition; another is a retweet in January about Shriver's father, Sargent Shriver, and memorial services being held following his death; the third is about Jack Lalanne's death.

Shriver, an even more prolific tweeter, hasn't mentioned her husband directly since Brown's election. She posted three updates on her Twitter page on the day of their 25th wedding anniversary, April 26, but did not mention the milestone.

About a month before the anniversary, Shriver wrote on her Facebook page that she was going through a transition in her life.

"As you know, transitions are not easy. I'd love to get your advice on how you've handled transitions in your own life," she said in a video posted on YouTube.

The breakup comes about four months after Schwarzenegger ended a bumpy, two-term run as California governor, a job his wife never wanted him to pursue. Since then, Schwarzenegger, 63, has been fashioning a role as an international advocate for green energy, giving speeches and lining up work in Hollywood. Shriver, 55, has guested-edited an edition of Oprah Winfrey's magazine but also talked about the stress of changing roles after serving as California's first lady.

Shriver moved out of the couple's gated estate in the Los Angeles neighborhood of Brentwood, but they remain on speaking terms. They had brunch with their children on Mother's Day in a tony restaurant in Santa Monica, and met privately on their wedding anniversary last month.

During Schwarzenegger's time in office, Shriver and the couple's children never moved to Sacramento, preferring their secluded estate a few miles from the Pacific Ocean. Schwarzenegger never settled in Sacramento, choosing instead to commute by private jet between his home and the state capitol.

Schwarzenegger and Shriver long presented a gilded partnership that crossed politics, Hollywood and media. They are known for charitable work, and he also founded a committee with New York Mayor Michael Bloomberg and Pennsylvania Gov. Ed Rendell to encourage road, bridge and other infrastructure development.

Shriver, the daughter of the late Eunice Kennedy Shriver, left her job as an NBC News correspondent after Schwarzenegger took office.

In a May 2009 commencement speech at the University of Southern California, Schwarzenegger alluded to the powerful influence Shriver had on his life. He said when people ask him the secret to success, "I say, number one, come to America. Number two, work your butt off. And number three, marry a Kennedy."

As the state's first lady, Shriver ran an annual women's conference that attracted a long list of business, political and entertainment luminaries, along with an audience of thousands. She also was credited with overhauling the California Museum in downtown Sacramento, and, with Schwarzenegger, starting the California Hall of Fame.

In 2007, Shriver said she wouldn't resume a TV news career after the media circus surrounding Anna Nicole Smith's accidental drug overdose.

"It was then that I knew that the TV news business had changed and so had I," she said at the time. In a 2009 interview with The Associated Press, she said "I'm too much of a free spirit" to consider running for elective office.

Shriver stood by her husband during his campaign after the Los Angeles Times reported accusations that he had a history of groping women; Schwarzenegger later said he "behaved badly sometimes."

The breakup comes months after the death of Shriver's father, Peace Corps founder and former vice presidential candidate Sargent Shriver, in January.

Schwarzenegger is attached to three upcoming movies, a new "Terminator" film, "Cry Macho," to be directed by Brad Furman, and "The Last Stand."
