Christopher Schwarzenegger Patrick Schwarzenegger the grove maria shriver suit divorce summer job

A mere two days after exiting the ER, Christopher Schwarzenegger looked healthy and happy as he visited big bro Patrick on the job, at The Grove, on Wednesday.

The 13-year-old was admitted to the ICU on July 17 after suffering a collapsed lung, broken bones and broken ribs from a boogie boarding accident in Malibu. Thankfully he was released on Monday and is expected to make quick recovery.

Chris, along with mom Maria Shriver and big sis Christina, 20, visited Patrick at the posh West Hollywood mall where he's working/interning for the summer -- directly under the malls owner, Rick Caruso. They also took some time to chat with Mario Lopez, who shoots a segment for Extra at the mall.
