Hailey and Justin Bieber dress baby Jack Blues in costume for first Halloween: See the pics

The Biebers are celebrating their first Halloween as a family of three!

On Friday, both Justin and Hailey Bieber shared photos of their “Kim Possible”-inspired costumes, with the model, 27, dressing up as the Disney Channel show’s lead while the “Baby” singer, 30, channeled her trusted sidekick Ron.

Their 2-month-old son, Jack Blues, also took part in the festivities, dressed as Ron’s pet naked mole rat Rufus.

In the snaps, Justin held the little one, who was covered up in a pink onesie, close to his chest. The new parents have yet to post any photos of their son’s face.

The couple matched black long-sleeved tops and baggy cargo pants with utility belts tied around their waist.

While Hailey got into character with a red wig, Justin added his own flare to the costume with a black hat and sunglasses.

The “Sorry” singer concluded the carousel with a cheeky photo of his wife touching his abs with her tongue out.

Despite being just a few months postpartum, Hailey pulled out all the stops for Halloween this year. Along with their family ensemble, Hailey also did a costume with BFF Kendall Jenner.

The two models recreated Paris Hilton and Nicole Richie’s iconic “Simple Life” poster, sporting near identical looks to the ones worn in promotional images from the 2003 show.

Hailey even recruited her and Justin’s dog Oscar for the shoot, who stepped in for the role of Hilton’s late dog Tinker Bell.

Justin and Hailey welcomed their son in August but have rarely shared glimpses of the newborn online.

Earlier this week, Hailey shared the first photo of her son after casting her ballot for the 2024 presidential election.

“Happy Halloween! Get out there and vote 👻,” Hailey wrote atop a photo of Jack Blue’s feet in a onesie with an “I Voted” sticker on his foot.

On Friday, the Rhode founder also shared another picture of her son snuggled up in a Halloween onesie.

While the happy couple have kept Jack Blues out of the public eye, the mother of one often sports sentimental pieces of jewelry in his honor.

Earlier this month, the model debuted a $5,000 HIE Hawaii bracelet engraved with “Jack Blues” to go with her diamond-crusted “JBB” bubble necklace and her diamond-studded “mom” ring.

The proud new mom also recently got a $2,800 Goyard Artois GM bag, monogrammed with “JBB” in green lettering.

The couple announced their pregnancy news in May while sharing photos from their vow renewal in Hawaii. They tied the knot at a New York City courthouse in September 2018 before hosting a bigger ceremony one year later.
