Rebecca Romijn To Appear On Project Runway

Tune into Project Runway tonight to see two of our favorite model moms share their fashion expertise.

Rebecca Romijn, who welcomed twins Charlie and Dolly with her husband Jerry O'Connell last December, will be appearing as a guest judge on the hit show. The Ugly Betty star will join a panel which includes Michael Kors, Nina Garcia and, of course, host Heidi Klum.

Heidi, who is expecting baby #4 with her husband Seal this fall, recently dished on her maternity style:

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. You just buy things in a size 10 - when you're doing a show on fashion, you still have to bring it on."
