Life's not always a beach for former California First Lady Maria Shriver -- but at least it was for a while this weekend.

Shriver, 55, warded off a scorching hot Southern California afternoon by taking a trip to the beach in Malibu with pals on Sunday.

The Chicago-born Kennedy family member wore a white beach tunic with gold patterns as she talked to her female pal, and doted on the woman’s adorable young daughter.

Maria Shriver had lunch on Monday with her son Christopher and daughter Christina and RadarOnline.com has the photos.

The trio dined in Brentwood, Calif. and while Christopher went super casual in shorts and a t-shirt, Christina wore a matching pair of shoes to her mother’s.

Shriver kept a tight grip on Christopher, 13, who was injured in a boogie-boarding accident last month, leaving him with a collapsed lung and broken ribs.

Arnold Schwarzenegger and Maria Shriver put their differences aside to spend some quality time together on his birthday Saturday.

The estranged couple met up in Beverly Hills for some retail therapy with their sons Patrick and Christopher.

Then it was off to Barneys New York, the high end retailer for some high end birthday shopping. Maria who had been at the nearby Ralph Lauren store, met up with their guys, and when last seen, they were all driving off together.

There's no hint of a reconciliation here. Arnold and Maria's divorce is still on the fast track, but the couple has obviously decided to keep it as amicable as possible.
