Arnold Schwarzenegger And Maria Shriver Divorce: Attend Dinner Party Separately

Arnold Schwarzenegger and estranged wife Maria Shriver attended the same birthday party Thursday night at Toscana restaurant in Brentwood, TMZ reports, though they arrived and left separately.

Since they announced their separation in May, Schwarzenegger and Shriver have been photographed at several Los Angeles restaurants, though never together. Schwarzenegger has been known to frequent Caffe Roma in Beverly Hills and grabbed a burger with 17-year-old son Patrick in Santa Monica last month. Shriver dined with kids Katherine, Christina, and Christopher at Tra Di Noi restaurant in Malibu over Memorial Day weekend.

Shriver filed for divorce two weeks ago, nearly two months after it was revealed that Schwarzenegger had fathered a child with former household staffer Mildred Patricia Baena.

The estranged spouses are in the beginning stages of hammering out their divorce settlement. TMZ reported last week that Schwarzenegger will remain in the family's Brentwood mansion while Shriver is buying a new $10 million home three miles away.
