The top Hollywood stylist, 39, is said to be at Cedars Sinai, where she'll deliver her first child -- a baby boy -- with husband Rodger Berman.

X17online reported that Zoe was pregnant (and seeking the advice of her former client and mother-of-two Nicole Richie) in early November, and the fashionista later confirmed the happy news on Twitter.

"Hey everyone! I want to officially confirm to my loyal friends and followers that I am pregnant," she wrote. "I feel great, Rodger and I are beyond excited and so thankful for all of your love and support."
