Heidi Klum won’t wear maternity clothes, femalefirst.co.uk reports.

The supermodel — who is seven months pregnant with her fourth child — says her role as host of Project Runway means she always has to look fashionable so she opts to buy larger sizes of her favourite designer collections to cover her expanding tummy.

“My stylist tries to find things that are not maternity clothes, so I’ve been wearing a lot from The Row, by Mary-Kate and Ashley Olsen. I love their clothes. Marc Jacobs too,” she said. “You just buy things in a size 10 — when you’re doing a show on fashion, you still have to bring it on.”

Klum’s fellow Victoria’s Secret model Adriana Lima is also pregnant, as are the company’s former faces Gisele Bündchen and Karolina Kurkova. Klum revealed her friends have been asking her for advice on motherhood.

“It’s so funny! We must have been with each other for so long now that our cycles and egg-dropping must have happened at the same time,” she said. “Adriana has asked me a few things about nannies and how the birth is. It’s hard to explain and you just have to kind of figure it out.”
