Kim Kardashian took to Instagram on Tuesday to share a candid photo of a family road trip. The reality star, who was making her way to San Diego to visit her grandmother MJ, snapped a photo of her daughter, North West, holding hands with her niece, Penelope Disick, in the backseat. Her nephew Mason Disick is also seen putting on a pair of sunglasses while sitting behind the girls. Kim captioned the photo, "ROAD TRIPPIN'." She also shared a group shot of herself, Khloé, Kris, and MJ, with the caption, "San Diego Sunsets with the fam."
North and Penelope's adorable display of affection isn't the first time we've seen them cement their BFF status. Earlier this Summer, the pair dressed up as mermaids while on vacation in St. Barts with their family. Kim also shared a slew of photos of them together in honor of Penelope's birthday.
