While on vacation in St. Barts over the holidays, stylist-to-the-stars Rachel Zoe refused to show off her mid-section and instead covered up with oversized caftans while everyone else paraded around in skimpy swimsuits. If you thought maybe she was just hiding the stretch marks gained from her first child, born in March, you'd likely be wrong. A source revealed to RadarOnline.com that the reason Rachel was hiding behind the oversized apparel is that she is already pregnant with baby No. 2.

The source works in the fashion industry and claims that Zoe admitted to a fellow stylist last month that she is already pregnant with her second child. The source said:

“Rachel 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! Both her and Roger are really, really happy though, and Rachel is hoping for a little girl this time round, although more than anything she just wants another healthy, happy baby.”
