Kate Bosworth For Topshop: Actress Sings In Retailer's Holiday Ad Campaign (VIDEO)

To be honest, we didn't get too wrapped up in the small hype leading up to Topshop's "big" reveal of which starlet will front their holiday campaign, complete with its very own hashtag (#whosthatgirl). So many actresses fronting fashion brands, so little time...

But, today, when we found out that Kate Bosworth is Topshop's new girl, we changed our tunes a bit. The actress stars in the retailer's Christmas movie, singing a sultry version of "Winter Wonderland" à la Michelle Pfeiffer in "The Fabulous Baker Boys" (seriously, that was the inspiration). The short clip was directed by Kate's fiancé, Hollywood director Michael Polish, and she looked beautiful and relaxed playing the role of lounge singer for her future hubby.

The "Blue Crush" star added yet another personal touch to the campaign by helping the Topshop team design the custom sparkly cocktail dress she wore in the video. And the good news is: the entire look, shoes and makeup included, will all be available for purchase. You can get the cosmetics via now and place your special, made-to-order request for the dress or shoes as well.

So if the high street store's holiday campaign lived up to your expectations: happy shopping! If not, there's always next season. Maybe they'll get Karlie Kloss again...
