Heidi may have gone topless for Project Runway's sexy new ad campaign, but in real life, she's just your regular super-mamma of four!

Klum is in NYC to promote Project Runway season 9, which will be the biggest season yet. This year the show will begin with 20 contestants, who each have to make a case to Klum, and judges Michael Kors and Nina Garcia and mentor Tim Gunn as to why they deserve a spot on the show.

Four will be dismissed ASAP, and the remaining 16 will begin "one of the toughest first challenges in the series' history" the following day.

This season's guest judges include Zoe Saldana, Malin Akerman, Kim Kardashian and Christina Ricci.
