Kate Mara and Johnny Depp are bringing Hollywood's blonde hair trend of the summer into the fall season! Over the weekend, Mara stepped out in West Hollywood with sunny new highlights, while Depp surprised everyone at the BFI London Film Festival Awards by accessorizing his polished suit with much lighter hair. Depp is no stranger to changing up his appearance to get into character (Edward Scissorhands, anyone?), but the jury is still out on whether or not his new 'do is for an upcoming role. Mara, on the other hand, hasn't altered her signature auburn shade for years, but the effect is more natural on her. While her red hair did give us serious envy, we think her pale blonde highlights and sandy gold low-lights are flattering, and we can't wait to see the chic sartorial picks she'll pair with her new look. Who do you think wears the color best? Tell us in the comments!
