Sideshow: What took Shriver, Schwarzenegger so long?

Why did Arnold Schwarzenegger and Maria Shriver wait until now to dissolve their 25-year-old matrimonial, financial, and political merger?

Haters might say they staved off the inevitable till Arnold un-govinated as California's ruler - a cynical ploy to protect Arnold's political position and power. But we're no haters.

"This has been a time of great personal and professional transition for each of us," the couple say. "We are continuing to parent our four children together," they added, referring to Katherine, 21, Christina, 19, Patrick, 17, and Christopher, 13.

Schwarz-love love never dies

Speaking of The Govinator Dynasty, the nation's foremost investigative journal, the National Enquirer, reports that Maria and Arnold's 17-year-old son, Patrick, has fallen prey to Miley Cyrus' good-(yet-oh-so-bad!)-girl charms. Some Anonymous Source Dude says Miley, who got Patrick's digits from Selena Gomez, "is looking to rope Patrick into a full-fledged romance."
