North West & Penelope Disick Celebrate Their Birthdays with Joint 'Moana'-Themed Party!

Cousins North West and Penelope Disick are celebrating their birthdays with an epic Disney party!

Kim and Kourtney Kardashian threw their daughters a joint Moana-themed birthday over the weekend where the girls were dressed in Polynesian-themed costumes and were joined by characters from the movie.

North – who turned 4 back on June 15 – and Penelope – who will turn 5 on July 8 – received their birthday gifts earlier this month with twin Pomeranian puppies.

Famous guests at the party included aunt Khloe Kardashian, Jaden Smith, and Larsa Pippen along with her daughter Sophia.
