“This is definitely sexier than past campaigns we’ve done,” Heidi tells PEOPLE. “I guess you could say ‘Hans and Franz’ are celebrating season 9.”

Heidi, her co-judges, Michael Kors and Nina Garcia, and mentor Tim Gun will all return for this new season, featuring celebrity guest judges like Kim Kardashian, Zoe Saldana, Christina Ricci and Malin Akerman and a group of 20 fresh aspiring fashion designers.
