Kim Kardashian and Lauren Conrad aren't the only ones slated to appear on America's Next Top Model cycle 12. A handful of models have also been tapped as guest judges by Tyra. First up? Chanel Iman, who will appear on the two-hour season premiere on Sept. 9. After that is Josie Maran, who will star in episode five, followed by Jessica White in episode six. Old-school Super Kristy Hume will lend her expertise in the eighth episode, while sexy Victoria's Secret siren Marisa Miller will join the fun on episode nine. Not that I mind a resident judge, but these guest judges are going to majorly spice things up.
