How does she do it?! Rachel Zoe is expecting her second child any day now, but she's not letting that slow her down or cramp her style. The 42-year-old fashion designer stepped out in West Hollywood on Tuesday, Dec. 10 wearing sky-high stiletto boots . . . at nine-months pregnant.

While heading to an office building with husband Rodger Berman, Zoe rocked a pair of over-the-knee, black platform boots. Fortunately, the pregnant star did appear to hold her husband's arm for balance. Zoe proudly showed off her big baby bump under a tight black shirt, and looked fabulously fashionable in a gray fur coat, large black handbag and round sunglasses.

The Rachel Zoe Project star appears to be in great shape nearing the end of her pregnancy. The famously slim star told Us Weekly last month that she won't be doing anything to lose the baby weight after giving birth. "Nothing. Chase a toddler and be a mother," she said of her workout plans. "Any new mother will tell you don't have to exercise, you just have to be a mom. Being a mom is the best exercise!"

Zoe and Berman are already parents to son Skyler, 2. The adorable little boy is gearing up to be a big brother. "I think he is getting there," Zoe told Us of her son. "He gets it that there is a baby inside me. It's taken a while to get him there, but he is getting there."
