sunglasses Rachel Zoe hat heels baby fashion

Looking chic in a long Missoni sweater layered over an all-black ensemble, matching hat and oversized glasses, Rachel Zoe carried her fashion-forward 10-month-old son Skyler down LA's Robertson Boulevard for full day of shopping Tuesday afternoon.

But is she carefully hiding a baby bump?

Rumors began to swirl that the celebrity fashion stylist is expecting her second child with hubby Rodger Berman, after she kept completely covered up during a recent vacation in St. Barth.

A source told RadarOnline.com that Zoe is "just past the three-month mark so she's hardly showing yet at all. She's thrilled, but, quite frankly a little shocked. She didn't think she would fall pregnant a second time, let alone so quickly."

If the rumors are true, we hope it's a girl!
