Those heels are "maj," as Rachel Zoe would say! The pregnant stylist and designer may be nine months pregnant — but that doesn’t mean she is going to give up her high heels!

The 42-year-old mom-to-be held on to husband Rodger Berman’s arm as she was spotted going shopping in Hollywood. Zoe paired her black stiletto boots with a belted black top, fur coat and an oversized bag.

Zoe and Berman already have a son, 2-year-old Skyler, who is gearing up to welcome a sibling. "He gets it that there is a baby inside me. It's taken a while to get him there, but he is getting there,” she told Us Weekly.

Zoe told SheKnows that she has a “uniform” she wears during and after pregnancy. "Jeans and a T-shirt with a good pair of boots was always my uniform during and after pregnancy," she said.

The mom-to-be also said she has considered creating her own maternity line. “Sure… there are some really great maternity options and I think a lot of designers have really come to the table with some beautiful maternity wear now,” Zoe said. “A Pea in the Pod has great stuff!”
