Nicole Richie has kick-started pregnancy rumblings again, after being photographed recently looking a little rounder in the mid-section. Nicole took her two children, Harlow and Sparrow (who are so adorable it almosts warms my little no-heart!), out to the park yesterday and what appears to be a baby-bump was seen. Mommy and kids hit the swings and played in the sandbox during their family outing, though husband/dad Joel Madden didn’t make the trip – He’s currently headed to Australia, where his band Good Charlotte has a string of tour dates lined up for the next three weeks.

Per X17:

We were too distracted by Nicole Richie’s beautiful kids Harlow and Sparrow to even notice it at first, but after we got a peek at her stomach, we have to ask what’s going on here! Is it possible that the 29-year-old starlet is expecting her third child with husband Joel Madden? Or is this just an unflattering shot of her belly?

Richie was also spotted yesterday as she made her way outta the gym, once again with a possible baby bump in full view. While there is no word yet on if she is or isn’t, it could just be a simple case of the ‘Christina Aguilera Bloated-Syndrome.’ But for now, just for shizz and giggles, we’ll add her to the bump-watch list until there is further confirmation or denial!

What do you think – Baby #3, or a yet-to-be digested cheeseburger?
