The Hangover (which opens this Friday) may be a total dude movie, but that didn't keep Hollywood's lovelies away from the red carpet last night.

Is Jenny McCarthy trying on hobo chic for size, or does she want people to speculate that she's with child? Cute shoes, though.

Ashley Olsen is dating Justin Bartha, who plays the missing groom in The Hangover. As is often the case with the non-acting Olsen, she wore a simple Calvin Klein dress with clean-looking makeup. This is a bit boring, but beautiful nonetheless.

Kendra Wilkinson's dress calls way too much attention to a particular area of her body, considering that area's just going to draw attention anyway. Otherwise, it's a classy look.

Sasha Barrese looks like she's channeling Blair Waldorf with the opaque tights and the tiny satin headband, does she not?

Kate Flannery (Meredith on The Office) looks much more attractive in real life than she does on her show. This shimmery dress perfectly complements her gorgeous red hair.

Jamie-Lynn Siegler's halter dress with a draping cowl is really quite sexy without revealing too much.

A Dolce & Gabbana dress is going to look sexy on anyone, but on Heather Graham, it goes beyond. She looks super hot, especially with those Jimmy Choos.

Kate Walsh's fitted Stella McCartney skirt and purple silk top are trés chic.

Briana Evigan is obviously worried about looking like she tried too hard.

Kristen Bell looks more beautiful in this Bryan Reyes dress than did the model who wore it during fashion week in February. Compliments on the nude peep-toe pumps.

MaryKate Olsen doesn't really care if anyone sees what she's wearing, apparently. But her Prada pumps can stand on their own.

Audrina Patridge looks classy, if not a bit wrinkly, in this silk brown dress. It's hard to keep that fabric wrinkle-free in a car, so she gets a pass.
