NASCAR World Joins Kyle Busch and Samantha To Celebrate Little B-Rex’s 10th Birthday

7 min read

Back in 2015, Samantha and Kyle Busch weren’t just fighting for wins on the track, they were fighting to become parents. After a tough road marked by infertility struggles and IVF treatments, their prayers were answered. On May 18, 2015, Brexton Locke Busch came into their lives. That moment wasn’t just special. It was life-changing. Samantha once wrote, “Words cannot describe how your heart swells with immense love the second you see your child for the first time and get to hold him.” Brexton’s birth became a chapter of hope for other families, too.

The couple used their experience to create the “Bundle of Joy Fund” to help others facing the same road. It wasn’t just any birth. It was the birth of a legacy. Kyle Busch, already one of NASCAR’s elite drivers, celebrated that year with his first Cup Series championship. But ask him what meant more, and he’d probably point to the moment he announced: “Samantha Busch & I welcome Brexton Locke Busch… Mom n baby doing great!”

For the Busch family, May 2015 was a month that changed everything as they stood stronger while fighting pain, uncertainty, and infertility. And now, a decade later, that miracle is ten years old. Little B-Rex isn’t so little anymore. And as the Busch family celebrated this huge milestone, the entire NASCAR world paused to wish Brexton a happy birthday. From fellow drivers to fans, everyone joined hands to honor the boy who had grown up right before their eyes.

A month of celebrations in the Busch household

May has been a month full of candles, cake, and celebrations for the Busch family. Kyle Busch kicked things off by celebrating his own birthday in the first week. The second week belonged to his daughter. And now, in week three, it was Brexton’s turn. Turning 10 is no small deal, it’s double digits and the start of a brand-new chapter in a young boy’s life, especially one who already lives in the fast lane. To mark the occasion, Kyle Busch posted a heartfelt tribute to his son on social media.

“Happy 10th Birthday to my amazing son @brextonbusch! I can hardly believe you’re already hitting this milestone—double digits, wow! You’re such a fantastic boy, a stellar race car driver, an adventurous fisher/hunter, and the best brother and son anyone could hope for. Your joy and personality brings happiness to all of us. I love you so much, and I can’t wait to celebrate you today! Here’s to another year of fun and amazing adventures!” he wrote on X with some adorable pictures.

That post quickly drew attention from all corners of the NASCAR world. It wasn’t just a proud dad moment; it was a celebration of the young racer many have watched grow up around the track. Journalists, fans, and drivers chimed in with birthday wishes. NASCAR insider Jeff Gluck even joked, “Only six more years until Brexton Busch can race on Truck Series short tracks and road courses.” That’s not far off, considering what Brexton has already achieved in grassroots racing, and that’s Kyle Busch’s plan as well!

In 2022, Kyle Busch spoke about his plans for a young Brexton, saying, “Brexton and I we share a truck when he turns 16 years old, when he’s 16 and 17. And then it’s his when he’s 18. And I’m done. I’m out. You know what I mean? Like that’s the perfect play.” Well, since then, Brexton has reached incredible heights in his young racing career, working to fulfill his dreams and Kyle Busch’s destiny.

Brexton’s resume is already impressive. He began racing at five and within a month, had his first win in the Beginner Box Stock division. As of his ninth birthday, he had notched over 100 wins in Bandoleros, outlaw karts, junior sprint cars, and micros. In 2024 alone, he picked up 48 wins and landed in the top ten 126 times. That’s not just talent, that’s consistency. In 2025, he won the Jr. Sprint Championship at the Tulsa Shootout and took home the coveted Golden Driller trophy.

Brexton also made headlines by racing against his dad at Millbridge Speedway and finishing sixth in a 20-car field. With such a strong base, the journey ahead looks bright, and Kyle Busch had some plans also. Busch hasn’t been shy about his hopes for Brexton’s future. And the journey to NASCAR isn’t a dream anymore, it’s a structured, well-planned path. As of this week, Brexton is now eligible to race in Legend Cars, a significant step in youth racing. On May 22, he will debut in an INEX Legends National Qualifier at Hickory Motor Speedway. Kyle recently explained, “He turns 10, he can’t race a Legend Car until he turns 10. That’s this week.”

Notably, Kyle draws inspiration from Kyle Larson’s son, Owen, who runs on all different types of tracks at age 10. “I look at tiny Kyle… the things he can do on dirt. Brexton should have that kind of flexibility.” It’s clear that this isn’t just about fun; it’s a serious development plan. Brexton is already being molded into a future star. But for now, the Busch family celebrated Brexton’s birthday with joy, and fans and fellow racers joined in too.

“Happy Birthday, B-Rex!” – The NASCAR world sends its love

The NASCAR community came alive with joy and nostalgia as Brexton Busch turned 10. From fans to legends, everyone had something to say about the little racer who’s growing up fast. His uncle and 2004 Cup champion, Kurt Busch, shared a heartfelt note: “Happy Birthday young man. Proud of you both on and off the track.” Kurt has often spoken about Brexton’s talent and said he reminds him of a young Kyle in the making.

One fan cleverly posted, “Happy birthday Brexton, a good present would be dad winning today.” Indeed, that would be a great gift. Tonight, Busch will be fighting for a million dollars in the NASCAR All-Star race at the iconic North Wilkesboro Speedway, and a win would surely light up the Busch household. Kyle Busch’s former teammate, Denny Hamlin’s fiancée, also joined the celebration, posting, “10 already?! How?! Happy birthday Brex.” The disbelief reflects how quickly the racing world has watched Brexton grow up. Just yesterday, it felt like he was sitting in the pit box with headphones on. Now, he’s suiting up himself.

Another comment summed it up perfectly: “Can’t believe that little squirt is 10 now.” It’s a reminder of how time flies, especially when someone grows up in front of a national audience. From his first time in the infield to now racing side by side with his dad, Brexton has lived a lifetime of racing in just ten short years.

From miracle baby to rising star, Brexton Busch’s 10th birthday became a celebration far beyond the Busch household. NASCAR fans, drivers, and legends all joined Kyle and Samantha to mark a decade of life, love, and racing. With his debut in Legend Cars just days away, B-Rex’s journey is shifting gears, and the whole sport is watching.
