ScarJo has to be the hardest working 24 year old celebrity spokesmodel in Hollywood. She already starred in ad campaigns for Calvin Klein, L'Oreal and Louis Vuitton. Now she's the star of a campaign for the new Dolce & Gabbana makeup line.

    Bar Rafaeli, Leonardo DiCaprio's stunning model girlfriend, is the face of British retailer Marks & Spencer's new lingerie line.

    Pam Anderson's new campaign for Vivienne Westwood is surprisingly hot. The blonde bombshell and her heaving, inflated bosoms aren't usually found in fashion mags -- but the quirky combo of Playboy centerfold and designer threads seems to work.

    Fergie for M.A.C.'s VIVA GLAM collection
    Fabulous, feathered, and just a little airbrushed.

    Katie and Posh's Dueling Ads
    We know it's tough to tell the difference, but that's Katie Holmes on the left for Miu Miu and Victoria Beckham baring (nearly) all for Giorgio Armani. The campaigns launched within days of one another -- so the question is: who's hotter?

    Madonna for Louis Vuitton
    Anyone else tired of the trademark Madonna crotch shot?

    Kirsten Dunst for Miu Miu
    We prefer Katie Holmes, hands down.

    Heidi Klum for Jordache
    The jean company was apparently trying to target the "hot mom" demographic.


    Kate Moss for Agent Provocateur
    Arguably the iconic lingerie maker's most famous star.

    Liv Tyler for Gap
    The actress helped boost the fledgling brand as it tried to overhaul its image.

The ads features Scarlett looking just like Marilyn Monroe (because Christina Aguilera and the late, great Anna Nicole Smith haven't quite squeezed every last bit out of that look yet) lying on a suggestively rumpled bed, in a very D&G corset. Clichéd, but very sexy.

Scarlett will be promoting He's Just Not That Into You, and then taking a few months off before her next movie starts. You have to admit, if you were married to Men's Health cover boy Ryan Reynolds, you'd want to hang around the house and wait for him to get out of the shower, too.
