Arnold Schwarzenegger’s son, 20-year-old Christopher made a rare appearance when he stepped out for a lunch date with his family.

He opted for a casual summer look with a light blue top and white shorts. He sported white sneakers with green accents and no socks.

There was also a long black brace on his right arm. It was unknown if he had sprained his wrist or is suffering from Carpel Tunnel Syndrome.

Maria was seen in sports gear with her phone on a cross-body handle. She also carried a takeout salad in one hand.

Her daughter, Katherine, sported skinny black jeans, a grey cropped sweatshirt. She also had a leather jacket flung over her shoulders.

The Brentwood School graduate, Christopher, is the youngest child of Arnold and Maria Shriver. The estranged couple is also parents to Katherine, 28, Christina, 27, and Patrick, 24.

Just a day before their lunch, Maria was seen struggling to carry her belongings while running errands. The 62-year-old looked stylish and was smiling despite the small mishap.

The NBC reporter filed for divorce in 2011. However, it came to light last month that she was still married to 70-year-old Arnold, according to Daily Mail.

Maria wanted to split after she learned that the former Governor fathered a child, Joseph Baena, with their housekeeper Mildred Patricia Baena.

The matter came to light in May 2011 when Joseph was 20 years old. The couple, who did not have a prenup, “quickly agreed on joint custody,” according to TMZ.

At the time of their separation, Arnold and Maria had an estimated wealth of $400 million. Sources quoted by TMZ said that though there were “bumps” during the settlement, there were “no serious roadblocks” since the split was 50/50.

Rumor mills are abuzz with the news that Arnold’s eldest child, Katherine, is dating “Jurassic World” star Chris Pratt.

Though the two have not confirmed their romance, they were spotted kissing each other after a church service on July 29, 2018, according to The Sun.

Accompanying them was Pratt’s five-year-old son, Jack, whom he shares with his estranged wife, Anna Faris.

The Sun reported that Arnold was taken to a hospital for an emergency heart operation. However, he is set to star in “Terminator 6” and even joked that he was “back” after the surgery.
