Nicole Richie spent the afternoon with her beautiful children, Harlow and Sparrow, and was snapped showing what might possibly be, a new baby on the way.

Richie and hubby Joel Madden were also spotted on Sunday, out for some afternoon toy shopping. Stocking up on supplies?

Richie [above] makes her way out of the gym in Studio City, California on April 5, 2011 – just a few moments after Kim Kardashian. Could these old friends be gym buddies?

Sunday marked the last bit of family quality time the Maddens will have in a while, as Joel headed to Asia for some new musical ventures.

He Tweeted early Monday that he was “off to manila” and that “if UR in indonesia, Malaysia, hongkong, bangkok & U want me to come Dj I’ll be over here for 3 weeks hit @mattavelli for booking. Holler!”
