Maria Shriver

Former California First Lady Maria Shriver and daughter Christina dined at Spago with Oprah Winfrey last night. They were joined by Christopher Schwarzenegger, 13, who was just released from the hospital after suffering a serious surfing accident last week.

Winfrey drove to the Beverly Hills hotspot from her home in Montecito, Calif. to sup with Maria and family.

Arnold Schwarzenegger and Maria Shriver's son Christopher, 13, headed home from the hospital Monday, after spending a week there following a surfing accident in which he suffered multiple broken bones and a collapsed lung.

Shriver tweeted Tuesday, "Blessed to be able to take Christopher out of the hospital last night. What a feeling of relief to know that he's going to be fine... We were very lucky. Many patients and families we met have been there so long and have no end in sight. I pray for their recovery.

Suffering from broken ribs and a collapsed lung, Christopher Schwarzenegger, 13, is still in the hospital recovering from a serious surfing accident, and his estranged parents Arnold and Maria are by his side.

Shriver called 911 following the accident saying, "He can't move... he's having trouble breathing."

The divorcing couple, reunited at their son's bedside, released a joint statement last week: "A few days ago our son Christopher suffered an accident at the beach. While it has been a very scary week, Christopher is surrounded by his family and friends. He is a brave boy and is expected to make a full recovery."

Former California First Lady Maria Shriver made the 911 call when her son, Christopher Schwarzenegger, was injured in a boogie boarding accident in Malibu.

Hear the call.

Shriver is heard explaining, "He can't move off the beach ... maybe like a broken ribs or something like that. It's my son ... he's awake and breathing; he just can't move. He's having trouble breathing."

The youngest of the Shriver-Schwarzenegger children, 13-year-old Christopher, was hospitalized after a serious surfing accident last weekend, reports TMZ.

The teen, in an Intensive Care Unit for days, suffered multiple broken bones and a collapsed lung while surfing in Malibu. Shriver has been by her son's side while he recovers at the hospital.

Christopher's current condition and the circumstances of the accident are not known.

The family, having been through a tough time after finding out Schwarzenegger fathered a son with the housekeeper, has been dealing with divorce proceedings. In his response to Maria's divorce petition, Arnold is asking not to be responsible for spousal support.

Former California Gov. Arnold Schwarzenegger has responded to soon-to-be ex-wife Maria Shriver's divorce petition by filing his own papers -- and he's asking not to be responsible for spousal support.

As first reported by TMZ, Schwarzenegger's lawyer is asking the judge to terminate any right on Shriver's part to receive spousal support, which she previously requested in her court filing.

The papers, obtained by "Extra," indicate Schwarzenegger and Shriver should pay for their own legal fees, rather than the actor paying the bill for both.

The Schwarzenegger document also says the couple has yet to determine how all of their property and assets will be divided.

There was no prenuptial agreement signed between the two, so under California law Schwarzenegger and Shriver are entitled to a 50/50 split of all earnings and property accumulated during their 25-year marriage. The two are estimated to be worth around $400 million.
