Kendall Jenner and Gigi Hadid aren’t only best friends, they’re both two of the fashion industry’s most sought after supermodels, walking down runways from Victoria’s Secret to Versace together. But it’s their latest couture catwalk that has us picking our jaws up off the floor. It seems that Jenner and Hadid have swapped hair colors for Paris Fashion Week’s fall-winter 2016 Balmain show.

Kendall, known for her deep brunette strands, sported a wavy blond style, while Gigi, who’s known for her surfer-girl, sun-kissed hair, rocked a chestnut brown hue. Although clearly a wig, we had to do a double take when scrolling through our Instagram feed.

After a closer look, it’s clear that the pair can easily pull it off—and momager Kris was unsurprisingly a big fan of her daughter’s newly highlighted look. She took to Twitter to say: “Blonde for @balmain! @kendalljenner #proudmama #parisfashionweek @gigihadid #repost @vogueparis.”

Although they weren’t the only ones to swap hair colors (Alessandra Ambrosio and Lily Donaldson did as well), these were definitely the most shocking. And the model besties were even spotted after the show still rocking their new ‘dos. Could this mean they might consider going for a real hair color transformation in the future? Only time will tell. But until then, borrowing Kylie’s wigs is an option.

Check out the fun hair color swap:
