Kourtney Kardashian shares Halloween photo with kids, North West

LOS ANGELES, Oct. 26 (UPI) -- Kourtney Kardashian delighted fans with a photo with her children and niece North West on Saturday.

The 36-year-old reality star posted a picture of herself, 5-year-old son Mason, 3-year-old daughter Penelope, 10-month-old son Reign and 2-year-old North in their Halloween costumes on Instagram.

Kardashian dressed in a Wonder Woman bodysuit, while Mason, Penelope and Reign sported similar superhero-inspired outfits. North was adorable as a white and pink unicorn.

The reality star is mother to Mason, Penelope and Reign with ex-partner Scott Disick. She and the 32-year-old club promoter were together nine years before splitting up in July after Disick was spotted with his ex-girlfriend, Chloe Bartoli.
