From Angelina Jolie's maternal instincts to Madonna's desperate attempt to recapture her youth, PopEater brings you the sartorial successes and big messes from the red carpets of Hollywood with our weekly Fashion Police.

This week is an interesting one, readers. Katie Holmes leads the pack, but we feature some people we don't usually see in our FP galleries, like Juliette Lewis, January Jones, Leona Lewis and Rachel Bilson. We hit up the Roberto Cavalli anniversary party (where we find the majority of our entries this week), and stop by the various movie premieres to catch stars like leading lady Katherine Heigl and cutie teen Chloe Moretz. Enjoy!
