Looks like Rooney Mara's about to find out whether blondes really do have more fun. The Academy Award nominee has adopted one of the biggest hair trends of the summer by going platinum. She was spotted sporting her new look in New York City recently while wearing a denim jacket, concert tee, and shades. Mara is definitely going for a beachy, surfer vibe with her latest hairstyle, which is quite a departure from the dramatically dark color she wore this past awards season.

The Carol star, who has rocked many different hairstyles over the years, joins stars like Taylor Swift, Kristen Stewart, and Emma Stone, all of whom have also recently tried out the hue. And with famous platinum blond Marilyn Monroe's birthday on June 1, we can only hope to see more inspired celebrities lighten up soon. Can't wait to see who's next!
