Wow, Marley Shelton looks as though her water is about to break right there on the red carpet. Normally that bright-red, cross-halter dress would look cute on Shelton, but perhaps her stylist should have mentioned that her girls are on the cusp of breaking free.

It's hard to say why Rumer Willis chose to wear a pre-wrinkled, corset-topped dress (with shoes that aren't working either). But her hot mama Demi Moore looks stunning as usual in a draped purple dress that shows just the right amount of skin.
