We hate to say, but we knew it! After some super-sleuth work late on a Friday afternoon, the Sugar crew concluded that Topshop's mystery new face must be Kate Bosworth. Why so sure? Well eagle-eyes Bella spotted her engagement ring in the first clip that was released (press pause around the eight second mark on the second teaser clip). Then we remembered her telling us during her stay in Sydney that she'd recently scored a slew of JW Anderson for Topshop goodies. If the ring fits! Directed by her fiancé Michael Polish, the festive-themed short film for the UK retailer sees Kate sing (yes, she can sing) atop a grand piano whilst wearing a custom-made backless bordeaux cocktail frock. Watch the big reveal, then go back to the sneak-peeks and see if you can see what we saw. Watch Kate walk in a Winterland . . .
