Lifetime told TheWrap that Kors is vacating his judge's position due to scheduling conflicts.

"Due to the back-to-back film schedule for seasons 10 and seasons 11 this summer, Michael was not able to commit to all the dates required for filming season 11," a Lifetime spokeswoman said in a statement. "Always part of the 'Project Runway' family, Michael will be seen in the future on the show, and we are excited to confirm that Michael will be back as a judge for the season 11 finale."

Kors' departure isn't the only change that's coming to "Project Runway" for its upcoming season. This cycle, the competing designers will be made to work together for every challenge, where they will have to work together while ensuring that their creations stand out on the runway. It's hoped this will lead to riveting combination of collaboration and backbiting.

Guests judges for the upcoming season include Bette Midler, Susan Sarandon, Miranda Lambert, John Legend, Emmy Rossum, Kristin Davis and others.
