Ellen Pompeo & Nicole Richie's Weekend Park Playdate

Taking full advantage of the beautiful weather, Ellen Pompeo and Nicole Richie were spotted out at Griffith Park in Los Feliz on Saturday (June 4).

The “Grey’s Anatomy” babe brought her daughter Stella and the “Simple Life” star had her son Sparrow and daughter Harlow in tow.

Ellen and Nicole have been maternity mates for awhile now, as they shopped for baby clothes back in 2009 when they were both preggers.

Later in the day, Ellen joined up with her husband Chris Ivery to pick up some to-go eats from The Grill in Beverly Hills.
