For the grand finale of Britain's X Factor, Adele and One Direction were invited as special guest performers. Adele graced the audience with a freshly chopped bob cut that just grazes her jaw line. There's nothing quite like snipping a few inches of your locks off after dropping one of the best-selling albums of the year. (To be exact, 25 is now past 5 million copies sold.) The 27-year-old was calm and collected as she sang her emotional single, "Hello." We love that Adele has opted for this shorter, layered style. Not only is it trés chic, but it shapes her radiant face nicely. Take a look at the cut in some posts from Instagram and watch a snippet of the performance, below.
