Rachel Zoe's second baby could come any day now, as she recently revealed that she is nine months pregnant.

The fashion designer flaunted her tiny baby bump in a gorgeous strapless black gown at the second annual Baby2Baby Gala in Culver City, Calif on Saturday.

Baby2Baby is an organization that provides baby supplies and clothing to families in need in Los Angeles.

In an interview with Us Weekly, Zoe said that she is nearing the end of her pregnancy and is excited to welcome the newest bundle of joy.

"It's wonderful. It's great," Zoe told Us of her second pregnancy. "I mean, I'm literally 9 months pregnant so this I think will probably be one of my last outings. I'm going into hibernation!"

"I'm tired," she added. "It's really hard to get really dressed up, but it's like you do it when it's important and tonight is really important."

Zoe already has her hands full with 2-year-old Skyler, but she said her son is excited to become a big brother.

"I think he is getting there," she explained. "He gets it that there is a baby inside me. It's taken a while to get him there, but he is getting there."

Zoe said she won't be going overboard and doing "nothing" out of the normal to lose weight after the baby arrives.

"Chase a toddler and be a mother," she said. "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!"
