Who’s ready for a bit of a brainteaser?

Topshop is about to launch its first-ever holiday campaign, and the store has asked us to help reveal its new celebrity face. So for the next few days, we’ll be posting some video teasers that might help you figure out who she is.

Have a guess? Tweet @StyleWatchMag and @Topshop using #whosthatgirl with your prediction, and you could be up for some super-cool Topshop prizes.

Check out the clip above, and the bonus photo below, then ponder this hint: You’ll eventually hear this A-lister sing in her ads. Good luck!
