Published: Nov 03 2025

I'll tell you once and for all: Jack Blues Bieber stole the show this Halloween. While time will ultimately reveal whether Justin Bieber and Hailey Bieber's 14-month-old son will follow in his dad's musical footsteps, he was certainly ready to take center stage on October 31st as he recreated one of the "One Less Lonely Girl" singer's most iconic looks.

Indeed, the Bieber household took a nostalgic trip back to 2010, as Jack donned Justin's My World Tour uniform—an all-white outfit with a purple hoodie peeking through. As Hailey captioned a trio of pics on Instagram, "Happy Halloween from JBB."

Of course, this was just the latest example of Jack paying homage to Justin's breakout era. Earlier in the month, Hailey shared a sneak peek at their son wearing a sweatshirt featuring his dad from around the time of My World 2.0's release.

But the Rhode Beauty founder didn't have to worry about not being able to make up her mind when it came to her son's Halloween looks. After all, she was armed with a second Halloween outfit for the toddler—this one embracing an incredible family theme.

Before teasing her toddler's twinning moment with Justin, she shared a glimpse into their Incredibles outfits, showcasing her as Mrs. Incredible before revealing Jack as, who else but the scene-stealing toddler Jack Jack. Her husband of seven years, meanwhile, completed the family ensemble by going as Mr. Incredible.

Over the last year, Hailey and Justin have opened up about their life as a family of three. And if Hailey has her way, they'll soon be adding new members to their group Halloween costumes, as she recently admitted she "definitely" hopes to further expand their family. "It's so fun," she explained on the October 24th episode of Owen Thiele's In Your Dreams podcast. "I always knew I wanted to be a mom. Since I was a little kid, I always envisioned myself having kids. You know what's funny? The older I've gotten and now that I have a kid, I think any decision anyone makes about having them or not having them is totally amazing."
