"It's nice to be out," the 42-year-old stylist told E! News while attending the 10th Annual Style Awards on Wednesday, Sept 4, in New York City. "I feel like I've been hiding for a long time and so it's kind of nice and then (glances at belly) here it is."
While her pregnancy was first reported by E! News back in June, a rep for Zoe had no comment at the time.
"We got away with it for six months," the fashionista said with a smile about being able to keep it a secret for so long. "But now I don't think I can hide it anymore."
As for how she's feeling the second time around, Zoe admitted, "I'm tired. I'm perpetually exhausted. But other than that, I'm fine."
She and husband Rodger Berman are already proud parents to 2-year-old son Skyler.
So is their firstborn looking forward to becoming a big brother?
"He's very excited," Zoe said. "But I don't think he wants to share his mom."
