Thirty-nine-year-old Fashionista's Cate Blanchett and Jennifer Lopez seem to have magically swapped places.

Lopez, who has been on a slow climb reclaiming her body and career since the birth of adorable twins Max and Emme, has finally hit a red carpet stride. After a series of over-the-top misses, Lopez delivers the goods reminiscent of her glory days.

In a stunning white Roberto Cavalli Grecian-gown, Mrs. Marc Anthony showed a bust and body that no mother of twins should have, a gorgeous bright face and hair worthy of a true diva.

Blanchett, on the other hand, always the impossible combination of a fan and critic fave, confused viewers in a bell-shaped Alexander McQueen number complete with micro-metallic detail and matronly flesh-tone cropped leggings.

Where's the accounting for the fashion Freaky Friday?

Perhaps Lopez is ready to reclaim her crown, and Blanchett is resting on her laurels?
