Watch: Justin Bieber & Hailey Bieber's Son Jack Is His Dad's Twin With Adorable Halloween Costume

I’ma tell you one time, Jack Blues Bieber stole this show this Halloween.

While only time will tell as to 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 the stage during the Oct. 31 holiday as he recreated one of the “One Less Lonely Girl” singer’s most iconic looks.

Indeed, the Bieber household turned back the clock to 2010, as Jack donned Justin’s My World Tour uniform consisting of 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 as earlier in the month, Hailey shared a 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, mind, mind, mind, mind when it came to her son’s Halloween looks.

Before teasing her toddler’s twinning moment with Justin, she shared a glimpse into their Incredibles outfits, showcasing her Mrs. Incredibles look before revealing Jack as, who else but 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, I love being a mom,” she explained on the Oct. 24 episode of Owen Thiele’s In Your Dreams podcast. “I always knew I wanted to be a mom, though. 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.”
