AceShowbiz - On Friday, November 1, Hailey Bieber took to Instagram to share a new glimpse of her son Jack's first Halloween celebration. In a photo captioned "October things," she showcased the 2-month-old's tiny legs and feet clad in an adorable skull-printed onesie, inspired by Jack Skellington from "The Nightmare Before Christmas."

The picture followed the Biebers' first-ever photo as a family of three, featuring Jack dressed as Ron's pet naked mole rat Rufus from "Kim Possible" while she and husband Justin Bieber, 30, dressed up as Kim Possible and Ron Stoppable. Justin lovingly held their son, who wore a pink onesie and matching hat.

Hailey and Justin welcomed their first child, Jack, on August 22. The couple tied the knot in 2018 following an on-and-off relationship. They announced her pregnancy in May while sharing pictures of their wedding vow renewal.

Justin has been open about his desire to start a family with his wife and he has been embracing his role as a first-time dad since baby Jack was born.
