More drama for the Schwarzenegger fam!

Arnold and Maria's youngest child, Christopher, was rushed to the hospital after a serious surfing accident last weekend, according to various online reports.

The 13-year-old was surfing in Malibu when the accident occurred, causing him to suffer multiple broken bones and a collapsed lung. A source tells PEOPLE: "Christopher has been in ICU since Sunday. Maria has not left his side and is sleeping at hospital."

Thankfully, he is expected to make a full recovery, according to reports.

In other news, Schwarzenegger recently filed documents asking a judge to terminate her spousal support request, even though Maria asked for it in her petition.

Arnold is also asking for joint custody of the pair's two minor children.
