14. Millie Bobby Brown
We didn't think Millie could get any cooler than she already is but... we guess she just did and ended the rest of us in the process. Walking the carpet at the Stranger Things 2 premiere, Millie added some subtle hair extensions to her short locks and looks almost unrecognisable! We wonder if she'll ever grow it back to the length it was before she shaved it all off?
