If you've spent even five minutes on TikTok lately, you've probably seen a middle-aged guy and his high-energy son screaming about double-chunk chocolate cookies. That’s AJ and Big Justice, the "Costco Guys." But while the father-son duo takes up most of the screen time, fans have been getting more and more curious about the rest of the family. Specifically, everyone wants to know: how old is big justice sister, Ashley?
She doesn't scream as much as her dad. She’s definitely more low-key than her brother, Eric (aka Big Justice). But she’s become a staple in the "Befumo Cinematic Universe."
The Real Age of Ashley Befumo
Let's get right to the point because nobody likes digging through twenty paragraphs for a single number. Ashley Befumo was born on February 8, 2010.
As of right now, in early 2026, Ashley is 15 years old. She’ll be turning 16 very soon, which is honestly wild if you remember when this family first started popping up on your For You Page. It feels like just yesterday they were just a random family from Florida (by way of New Jersey) making goofy food reviews. Now, they’re basically the royal family of warehouse retail.
Why Everyone Is Searching for Big Justice’s Sister
It’s kinda funny how the internet works. You start off watching a kid named Big Justice hit a "boom" in a Costco aisle, and suddenly you’re invested in the birth dates of his entire extended family.

Ashley—often referred to by fans simply as the "sister"—represents the more "normal" side of the Befumo household. While AJ is out there wrestling and Big Justice is becoming a certified pre-teen icon, Ashley is just... a teenager. Her presence in the videos adds a layer of relatability. She’s often the one reacting to the chaos around her, which honestly, is how most of us feel watching their videos.
A Quick Family Breakdown
If you're trying to keep the ages straight for the whole crew, here is the current 2026 lineup:
- AJ Befumo (Dad): 50 years old (Born January 16, 1976).
- Ashley (The Sister): 15 years old (Born February 8, 2010).
- Big Justice (Eric): 12 years old (Born April 8, 2013).
- Erika (The Mom/MBJ): 47 years old (Born July 15, 1978).
Is She Part of the Brand?
Honestly, yeah. While she isn't the face of the "We Bring the Boom" movement in the same way AJ and Eric are, she’s leaned into the family business. You’ve probably seen her in the "Boom or Doom" segments. Usually, she's the voice of reason or at least the one trying to eat her food without getting hit by a stray elbow from a celebration dance.
There was a lot of talk online a while back about whether the kids were being "forced" into content. But if you watch the behind-the-scenes stuff, Ashley seems to genuinely enjoy the perks. I mean, who wouldn't want to travel and eat snacks for a living? Plus, she’s managed to maintain a bit more privacy than her brother, which is probably a smart move for a 15-year-old.

Life Outside of Costco
Before they were the Costco Guys, the Befumos were living a pretty standard life in Colts Neck, New Jersey. They eventually moved down to Boca Raton, Florida. That’s where the "Costco Universe" really exploded.
Ashley grew up in the shadow of her dad’s wrestling career—AJ used to wrestle as "The American Powerchild Eric Justice"—so being around cameras and "characters" isn't new to her. It’s basically the family trade at this point.
People often confuse the "Rizzler" (Christian Joseph) with being a sibling, but he's just a family friend. Ashley is the only sister in the immediate Befumo household. It's a tight-knit group, and despite the loud "BOOMS" and the frantic energy, they seem like a pretty supportive unit.
The "Boom" Factor and Growing Up Online
It’s gotta be weird being 15 and having millions of people know your name because your dad likes bulk-buy muffins. But Ashley handles it well. She’s managed to build her own small following without losing that "regular kid" vibe.

The biggest challenge for her right now? Probably just being a sophomore in high school while her family is a living meme. Most kids are worried about chemistry tests; she’s worried about which viral sound her dad is going to make her use next.
Basically, she’s the anchor. Without her and Erika (Mother of Big Justice), the videos would just be two guys shouting in a parking lot. They provide the "family" in family-vlogging.
If you want to keep up with her specifically, she occasionally pops up on her own social channels, but most of the action stays on the main AJ & Big Justice accounts. Just remember: she’s 15, she’s a Pisces, and she’s probably the most tired person in that house after a long day of filming.
Keep an eye on the channel for her 16th birthday content—you know AJ is going to do something massive for that. It’ll probably involve a lot of balloons, a lot of food, and definitely a very loud "BOOM."
