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.

This week, we grab here and there from various celeb events. Up top is Megan Fox in a revealing red dress, triggering memories of J.Lo's at-the-time groundbreaking plunging V. It doesn't work so well for Ms. Fox. Also, we catch a glimpse of the never-aging Joan Collins and get a back shot of some bunched-up shorts on Cameron Diaz.
