Maria Shriver's son is expected to be released from the hospital this week following his treatment for injuries sustained during a boogie-boarding accident in Malibu, People reported.
The 13-year-old was admitted to an L.A. hospital July 17 with a collapsed lung, broken bones and broken ribs.
Shriver has reportedly spent every day and night at the hospital since the accident. She is said to have been on the Malibu beach when Christopher -- son of her estranged husband, Arnold Schwarzenegger -- got caught in the big wave.
Shriver is in the midst of divorcing Arnold Schwarzenegger, who earlier this year admitted that he had fathered a child (born just one week after Christopher) with their longtime housekeeper, Mildred Patricia Beana.
She filed for divorce over the Fourth of July weekend, seeking custody of Christopher and their other underage son, Patrick.
The couple, who were married 25 years, also have two grown children.
