As the latest face of Topshop and newly engaged, Kate Bosworth has something to sing about! The Blue Crush actress teamed up with her fiance, director Michael Polish, in a new, sexy commercial for Topshop that showcases her impressive singing in a rendition of Winter Wonderland.

Bosworth, 29, is dressed in a custom-made evening dress, created with the help of the Topshop design team, for the seductive ad that is a throw-back to the days of sexy lounge singers and smoky bars. Bosworth even goes as far as to drape herself across a grand piano. Polish, who directed the commercial, was inspired by Michelle Pffeifer's famous piano scene in The Fabulous Baker Boys.
