Kourtney Kardashian Kick-Starts Halloween With Her Adorable Super Squad

Kourtney Kardashian is getting a head start on Halloween! The mom of three shared a supercute photo of herself, along with her kids Mason, Penelope, and Reign Disick, dressed up as superheroes on Saturday. Also featured in one of the Instagram snaps was Kourtney's niece North West, who went rogue in an adorable unicorn costume. It appeared that Kourtney and her mini squad, all dressed in looks from Pottery Barn Kids, were at an early Halloween bash, so they'll likely switch it up for the big day.

Kourtney's day with the kids comes after she spent Friday evening partying it up with her older family members, mom Kris Jenner and sisters Kim Kardashian and Kylie and Kendall Jenner, at a birthday celebration for Balmain designer Olivier Rousteing. The bash also brought out Jada Pinkett Smith and her kids, Jaden and Willow Smith, as well as Kate Hudson, who arrived in a sexy gold dress.
