Kyle Busch’s son Brexton pens a birthday note for ‘officially old’ NASCAR champion

NASCAR legend Kyle Busch recently celebrated his 40th birthday and received countless wishes from fans and fellow drivers across the NASCAR world. Among the most special was a heartfelt message from his nearly 10-year-old son, Brexton, which Busch proudly shared on his social media.

Two-time NASCAR Cup Series champion Kyle Busch is one of the most decorated drivers in the sport’s history. The Las Vegas native has amassed 232 victories across NASCAR’s top three divisions. With 63 Cup Series wins—ninth all-time—Busch also holds multiple records in both the Xfinity and Truck Series, showcasing his dominance across all levels.

The former champion has played a pivotal role in shaping Brexton Busch’s budding racing career. Their shared passion for the sport is evident in Brexton’s early success and the strong bond they’ve built through it. Marking his dad’s 40th birthday, Brexton shared a heartfelt message on X, along with a few touching snapshots of the duo, writing:

"Happy Birthday to the best Dad!! Thanks for all the lessons and fun on and off the track! I can’t wait to race against you again! Also, I think 40 means you are officially old! Go get em this weekend!"

Since his switch from Joe Gibbs Racing to Richard Childress Racing, Kyle Busch has faced a challenging stretch in his Cup Series career. Now behind the wheel of the No. 8 Chevrolet, the two-time champion will be aiming to snap his winless streak at the Wurth 400, potentially turning his 40th birthday into an unforgettable celebration.

Catch the Cup Series race at Texas Motor Speedway on Sunday, May 4 at 3:30 PM Eastern time, exclusively available on FOX Sports 1, Performance Racing Network, and SiriusXM's NASCAR channel.
