Models change up their look all the time: Just ask Kendall Jenner or Gigi Hadid, who have gone so far as to swap hair colors. In fact, change is pretty standard when it comes to the runway, but turkey day must have brought out Bella Hadid鈥檚 (now a Nike spokesmodel) adventurous side, because she went rogue and totally changed up her look on us, just for fun.

Posting a pic of herself cooking a feast (mac and cheese, if you must know 鈥 so right in line with her laissez-faire diet), Bella showed off her new flippy blonde bob in a plain mauve tee and a smoldering stare.

Whoa! If we didn鈥檛 know any better, we鈥檇 think this was a retro snap from the 鈥70s of an everyday bombshell whipping up some Thanksgiving dinner!

It鈥檚 not the first time she鈥檚 traded hair hues with sister Gigi: Back in June, she posted this snap of herself as a blonde with dip-dyed cotton candy pink ends.

We can only assume both looks were wigs (a rising trend for hair damage/loss), because both times, she was right back to being brunette the very next day.

Who knows? Maybe she鈥檒l surprise us and rock it in her Victoria鈥檚 Secret fashion show debut on December 5?

We can鈥檛 wait to find out!
