Earlier today, Kim Kardashian shared an Instagram photo of her and Kanye West's daughter North cuddling with Penelope Disick. Kim added the caption, "BFF," which stands for best friends forever, if that somehow flew over your head. The picture above is a bit of a family affair, as North and Penelope are cousins. Penelope is the one-year-old daughter of Kim's older sister Kourtney Kardashian and partner Scott Disick
