Here's your first 2013 (style) shake-up: Zac Posen will replace Michael Kors as a judge  on the new season of Project Runway, which airs Jan. 24. The reason for the change? Scheduling conflicts on Kors's part. Posen, who's no stranger to the panel (he's appeared on the show as a guest judge in the past), tweeted earlier , "So excited to be the new judge on @ProjectRunway Season 11!" And, while the show's host and executive producer, Heidi Klum  shares Posen's excitement — she took to Twitter to welcome him — she also tweeted , "I will miss you this season my brother @Michael Kors I love you!" This won't be the last you'll be seeing of Kors, though. He'll take up his judging post for the show's always epic season finale. Now that you've had a few seconds to process the news, we want to know your thoughts: are you excited to have a fresh face on the panel lineup? Or, are you sad that Michael Kors won't be a permanent Project Runway fixture anymore?
