My celebrity hair makeover obsession of the moment: Karlie Kloss as a new blond!

Here she is posing with photographer Mario Testino.

Karlie was always blondish, but as you can see, she has taken her color a few shades lighter, with help from famed hairstylist Garren. (A move that only makes her look even more like pal Taylor Swift’s long-lost twin.)

Meanwhile, check out the new Balenciaga ads featuring Gisele Bundchen with a buzz cut!

None of us thinks Gisele actually cut hair off for these photos, but still, isn’t it fun to see her in such a fierce hairstyle?

What’s your reaction to these two supermodel hair change-ups?
