Plus, the former governor of California is spotted dining in Beverly Hills over the fourth of July weekend.

Former California governor Arnold Schwarzenegger isn't hiding out after his wife, Maria Shriver, filed for divorce Friday.

Schwarzenegger was spotted having lunch at his usually spot in Beverly Hills, Cafe Roma, on Saturday afternoon.

He was smiling, but silent when caught on camera with cameras. He dined with a number of friends, the website reports.

In May, the couple of 25 years announced they were separating shortly after Schwarzenegger admitted to fathering a child with the family's longtime housekeeper, Mildred Baena.

"This has been a time of great personal and professional transition for each of us," the couple told the Los Angeles Times in a statement then. "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."

Baena gave an interview to Hello! magazine describing her confrontation with Shriver about the children.

It appears from the divorce filing that the couple did not have a prenuptial agreement.

MoneyWatch reports that the couple are worth at least $200 million and maybe up to $400 million. (They are so well off, in fact, that Schwarzenegger donated his entire California governor’s salary of $206,500 to charity; he also flew by private jet -- his own -- to Sacramento for gubernatorial duties at a personal cost of hundreds of thousands of dollars year, the L.A. Times reported.)

TMZ puts their worth closer to $400 million, saying that Schwarzenegger is worth $300 million and Shriver $100 million.

According to the Associated Press, Schwarzenegger -- who starred in blockbusters The Terminator and True Lies -- has interests in at least eight entities of $1 million or more, according to disclosure forms filed when he finished his term as governor.

Shriver, a member of the Kennedy dynasty, is  worth at least $1 million, including book royalties. She stepped down as an NBC anchor and journalist when her husband ran for governor.

California is a community property state, meaning that they money they earned during a marriage is co-owned by both husband and wife, regardless of who actually earned it.

They also have four children together.

Since leaving office, Schwarzenegger has signed on to star in the drama Cry Macho. His reps at CAA also are shopping a package for a new Terminator sequel. In addition, he has partnered with Stan Lee on a Governator comic and animated series, with plans for a movie as well.

Shriver runs a women's empowerment website and served as a guest editor on an issue of Oprah Winfrey's magazine, O.

The couple's marriage faced challenges in 2003, when Schwarzenegger was running for governor of California. Various media outlets reported on his history of groping women, but Shriver defended him at the time.
