They're the cutest squad in Hollywood.

Kourtney Kardashian shared a adorable photo of herself and her three children wearing superhero-themed Halloween looks -- plus her niece North West, 2, wearing a unicorn costume -- on her Instagram page on Oct. 24.

Kourtney, who was dressed as Wonder Woman, captioned the shot of her caped kiddos -- Mason Disick, 5, Penelope Disick, 3, Reign Disick, 10 months -- plus sister Kim Kardashian West's daughter -- with a simple word: "Squad."

She followed it up with a snapshot of just her own brood alongside a series of crime-fighting-inspired emojis, "⚡️🎯⭐️."

Kourtney's kids' father, Scott Disick, was notably absent from the photos: He checked into a Malibu, California, rehab facility in early October.
