While Kesha has gone back to long, luscious locks for summer and Victoria’s Secret model Taylor Hill has chopped her hair off into an edgy pixie cut, Rooney Mara has made her own dramatic ‘do transformation. Ditching her signature dark shade, it’s a new blonde look for Rooney. We’re talking platinum blonde, and as shocking as the change is, it’s the perfect choice for the sunny summer months ahead.

Rooney was spotted around town casually dressed in a denim jacket and loose tee, her light-rimmed sunnies edged along her still-dark brows. But it’s the hair that’s making jaws drop. Kinda shaggy and pulled back so we can’t quite get the full effect, her hair appears to be longer at the moment than her usual mod-like bob.

Is it for a role (she’s playing the title character in the upcoming Mary Magdalene pic, but this doesn’t feel very Mary Magdalene-ish)? Did the 31-year-old just feel the need for a major change? Will the color be around when the cooler weather hits, or will she be going back to her darker shades ASAP? We’ll just have to watch and see.
