North West and her cousin Penelope Disick proved yet again that they are the best of friends holding hands as they stepped out in Calabasas, Los Angeles on Sunday with their families. Disick, 4, who is the only daughter of Kim's big sister Kourtney and Scott Disick, and her three-year-old cousin could have passed for sisters as they enjoyed a fashionable play date. Nori supported her rapper-turned-designer dad, Kanye West, in a sporty green two-piece sweat suit from his Adidas line, which she styled with black sneakers, two mini buns, and a purple bracelet, while Penelope channeled her street-style know-how with a casual checkered shirt, black skinny jeans, black kicks, and a too-cool black leather jacket with a fur collar. Proud mom Kim couldn't resist sharing a photo to her Snapchat of the stylish girls, in which North makes a face at the camera while Penelope turns her face away, which the reality star hilariously captioned, "Thrilled to party!" kimkardashian/Snapchat VIDEO: The Cutest Celebrity Kids on Instagram North West's and Penelope Disick's Outfits Won Valentine's Day Looks like these toddlers are already a major fashion force to be reckoned with!
