Topshop you’re such a tease! The second installment of the Topshop Who’s That Girl Social Media campaign has been released. It’s becoming a worldwide guessing game via Twitter as Tweeple from Japan, Australia, the US, the UK and the rest of the world try to determine the identity of the mystery girl using the hashtag #WhosThatGirl. It’s clear from this picture she’s a blonde. More than that I can’t say. You’ll want to guess to be entered into a prize draw for some holiday shopping! Follow the Tweets from Topshop and me to pick up some clues to tell you who the mystery lady is. One lucky entrant will win a prize for guessing who the mystery lady is. Watch the second teaser video, then go to www.topshop.com/whosthatgirl to register your guess for a chance to win a £500 shopping spree (approximately $802 USD). Here’s the next installment in the #WhosthatGirl saga. Hint: I don’t think it’s Madonna in a repeat performance of her dreadful 80’s Who’s That Girl film. Although in this second teaser video it certainly sounds like the girl is about to part her lips and sing. Listen for yourself.
