Rooney Mara is trying to find out if blondes have more fun. The Carol star was spotted over the weekend with platinum blonde hair à la Kristen Stewart and Taylor Swift.

rooneyThe 31-year-old debuted her Targaryen-like hair while walking her pooches in a grunge-inspired outfit. It certainly seems to be the summer of blondes – Emma Stone and Rachel McAdams have also made the switch to bright blonde. Perhaps that’s what inspired Mara and her colourist, Cassondra Kaeding, to make the big change.

“I’ve been lighter, but I prefer being brunette,” she told InStyle in the past. “I find that people with dark hair don’t need to wear as much makeup.”

Perhaps she had a change of heart, or maybe it’s for a role, but either way we’re loving the shocking change. Rumour has it Mara is in talks to play Mary Magdalene in Garth Davis’ latest film. Joaquin Phoenix is said to be in talks to play Jesus Christ himself.
