Hailey Bieber is sharing another glimpse of her son Jack’s first Halloween!

On Friday, Nov. 1, the new mom, 27, posted a cute new photo of her 2-month-old son Jack in a skeleton onesie as she and her husband Justin Bieber marked their first Halloween as a family of three.

In a post captioned “October things ✅✅😌,” she shared the adorable snap which showed Jack’s legs and feet as he lay down wearing a black and white skull-printed onesie (which appeared to feature the character Jack Skellington from the 1993 film The Nightmare Before Christmas) and matching white socks, right on theme with the spooky holiday.

Hailey also shared a cute photo of her son Jack in a second Halloween costume — as Ron’s pet naked mole rat Rufus from Kim Possible —  while she and Justin, 30 dressed up as Kim Possible and Ron.

In the snap, Justin held their baby boy, who wore a pink onesie and a matching hat. Justin wore a black cap and oversized sweatshirt with baggy cargo pants and a khaki green utility belt.

Other photos included in her initial post showed Hailey posing solo in her Kim Possible outfit and other selfies taken at various different times throughout October.
