Arnold Schwarzenegger and Maria Shriver's 13-year-old son Christopher is hospitalized in serious condition after a recent surfing accident in Malibu.
A source close to the family tells ET that Christopher was boogie boarding last Sunday when something went wrong and he suffered a collapsed lung, broken bones and broken ribs. His mother was with him on the beach after the accident. He remains in ICU at a Los Angeles area hospital, but the source said: "Christopher is doing better. He is going to be okay"
