The Kardashians chose Saturday, June 24, for the joint party as a middle ground between the birth dates of the cousins. She wore a printed two-piece decorated with bright leis and a lovely Hawaiian-style flower crown. Kourtney and her friends couldn't resist a photo op with the ocean-themed toy, posing together on the surfboard in this cute 'Gram. "Happy bday Penelope", she added to another snapshot.
The birthday girls' auntie, Khloe Kardashian, and model Daphne Joy, posted photos with comments about the birthday party to social media. Penelope named hers honey. Guests enjoyed barbecue ribs, macaroni and cheese, rainbow shaved ice and birthday cake. Joy also caught her son Sire aiming for the girls with a water gun in the pool.
Us Weekly noted that the party was low-key compared to the lavish parties that Kim threw at North's first, second and third birthdays. The adorable cousins each looked the part of a Polynesian princess, with North wearing a bright two-piece outfit with floral crown, while Penelope channeled her inner Moana with a brown wig and lookalike costume, complete with the Disney charcter's famed necklace.
Kim, 36, recently shared a picture of the tiny white pups, which appear to be of the Pomeranian teacup breed, on Instagram and wrote: "Sister puppies for North & P!"
"Please help us pick the final name!"
Kim - who also has 18-month-old son Saint with her "Famous" rapper husband Kanye West - also took a video with North's puppy kissing her neck, and asked: "You guys how cute is North's little puppy?"
