At last night’s Kate Young for Target launch event, the seemingly shy and demure Michelle Williams showed up with a brand-new, rather punky haircut … with a buzzer taken up one side to keep at least one ear cool this spring. A few months ago, during her Oz the Great and Powerful press tour, Williams told E! News that she was planning to grow out her post-Ledger gamine cut. We assumed that she’d transition into a stylish, chin-skimming bob, but perhaps she looked instead to our favorite Barbadian hair chameleon, Rihanna, for some style inspiration. This particular Rihanna cut (circa 2009) — a partial buzz cut with a longish, eyelash-tickling forelock — was also spotted on the Biebs recently. Who will sport the warm-weather look next? MObama, perhaps? It would be one way to breathe new life into those bangs.
