It's a good thing there will be 20 new designers to make the supermodel some clothes! "This is definitely sexier than past campaigns we've done", she told People Magazine. "I guess you could say 'Hans and Franz' are celebrating season 9."

The new season, which premieres July 28 (9 p.m. ET) on Lifetime, features Klum and her influential co-judges Michael Kors and Nina Garcia, as well as several celebrity judges, including Kim Kardashian, Christina Ricci, Zoe Saldana and Malin Akerman.  Inventive fashion, exasperating drama, and designer mentor, Tim Gunn, are all sure to return this season!
