Very exciting news for this mystery model!

In a pretty mysterious move, Karen Millen have released a teaser trailer to show off the star of their autumn/winter 2014 range… but all we get to see is the back of her head. 

The stunning red hair might be a clue but KM are keeping tight-lipped for now. Watch the video for yourself above – it's got some gorgeous shots of East London. Maybe you'll have better luck guessing than we did! 

By sharing the video on Facebook or Twitter with the hashtag #KMTHEJOURNEY between now and Friday afternoon, you could also bag yourself a piece from the label's new season collection. We've definitely got our eye on a few things!
