Katy Perry made a splash during fashion festivities while in Europe in early 2012, with a blinding blue updo.

It was Smurf-blue, and given the fact that she voiced the role of Smurfette in the film version, we can understand her decision to throw her hair into a chic chignon that got an extra pop thanks to the color.

Doesn't she look otherwordly, mixing a First Lady 'do with a punk rocker's hue?
