By now we're all aware of CaKe, the ship name for besties Cara Delevingne and Kendall Jenner, but the name KenGi isn't as familiar. While Kendall and Gigi Hadid's own ship name is fairly new to those of us, the two have been friends since they were kids. And now they've got the jewelry to prove it.

Gigi posted a photo on Snapchat of herself last night wearing a delicate necklace featuring the name "KenGi," along with the caption, "ITS LIT." While we've yet to see Kendall rock her own, she has been to known to sport friendship jewelry in the past. Like, the exact same necklace but with a different name.

Yup, back in September Kendall showed off her necklace in support of CaKe while walking through the airport -- and lest we forget those matching shirts. It seems like you can never have too many best friends or too much friendship swag.
