What has happened to Bradley Cooper’s hair?

It's like he got nominated for an Oscar and all hell broke loose - on his head. #hairhangover
There’s no denying that Bradley Cooper is one helluva good looking guy; with piercing blue eyes, a chiselled jaw akin to that of Michaelangelo's David, and a lupine grin that borders on the indecent. Coops is so friggin' perfect, we reckon if we ever actually clapped eyes on him in person, we'd probably combust.
