Arnold Schwarzenegger Lunches With Son Patrick Schwarzenneger

Patrick Schwarzenegger, who recently changed his last name on Twitter to "Shriver," spent some quality time with his father Arnold Schwarzenegger on Thursday--the first time the two have been photographed together since news of Schwarzenegger's love child broke.

Schwarzenegger and his eldest son had lunch at Umami Burger in Santa Monica, California. They were joined by several California Highway Patrol officers, who were recently accused by the National Enquirer of covering up Schwarzenegger's extramarital affairs (the officers denied the allegations).

"[B]out to grab an unami burger which is the best! Going with a few of the CHP officers that worked with my fam for last 7 years. Cant wait!" Patrick Schwarzenegger tweeted on Thursday.

The day after Schwarzenegger admitted to fathering a child with former housekeeper Mildred Patricia Baena, Patrick Schwarzenegger tweeted that he would stand by his family: "Some days you feel like shit, some days you want to quit and just be normal for a bit, yet i love my family till death do us apart," he tweeted.
