Kaia Gerber is officially a blonde -- temporarily, that is!

The 14-year-old model, who is naturally brunette, took to Instagram on Friday to share a snap of her sporting short, platinum blonde tresses. According to her caption, however, the new look was all just for fun.

"Just a lil wig :)," she wrote.

Her 420K followers were quick to comment on the dramatic 'do, writing things like, "How does she look good either way? I don't get it!" "So Gwen Stefani," and "Kaia, it looks like it's your real hair roots and everything. I guess wigs have come a long way!"

Real or not, one thing's for sure -- even with her lighter locks, Gerber still looks like a spitting image of her supermodel mama, Cindy Crawford.

Earlier this week, Crawford and her mini-me daughter -- whom she shares with Rande Gerber -- shared their first-ever joint cover for Vogue Paris' April issue, in which the two brunette beauties appear almost identical in matching leather jackets and hoop earrings.

"What is life?!! I honestly can't breathe right now. a million thank you's to @vogueparis & @mariotestino!!" Gerber adorably captioned the pic, shot by famed fashion photographer Mario Testino.

Crawford, 50, echoed her daughter's statement, captioning her post, "Such a special moment sharing a cover with my daughter -- April issue of @VogueParis!"

Last October, Gerber turned heads in a strapless Emporio Armani dress while attending a party for the teen version of the high-fashion glossy. She even sported Crawford's signature tousled hairstyle at the star-studded young Hollywood soiree.

At the time, an eyewitness told ET that the teen had clearly been taught how to pose, as she was flipping her hair and expertly smiling on the carpet. Hear more (and see the stunning pics!) in the video below.
