A few days before his untimely passing, Kyle Busch had celebrated his eldest child's birthday. On Thursday, May 21st, the two-time NASCAR Cup Series champion succumbed to a "severe illness" hours after his family had announced his hospitalization. He was just 41 years old.
Prior to his demise, the sports star, who shared two children with his wife Samantha Busch—Brexton Locke, 11, and Lennix Key, 4—was surrounded by his loved ones as they marked Brexton’s 11th birthday on Monday, May 18th.
"Happy Birthday Brexton!!!" Kyle wrote in a heartfelt social media tribute to his firstborn. "Your mom & I are so proud of who you're turning out to be!" the proud dad continued. "You're the best kid on & off the track, you amaze us every day. Keep doing what you're doing, and there's no limit to what you'll accomplish! Love you buddy!"
His Instagram carousel began with a group photo of him and Samantha, 39, standing with their two kids at a racetrack for a sports car-themed celebration. Brexton held up a trophy, much like his dad had over the years, while his little sister waved a checkered flag. Kyle and Samantha each held up their fingers, symbolizing "No. 1" as they all smiled for the photo op. Another image showed a baby Brexton standing in his father's lap in a mini go-kart.
Samantha also shared sweet family moments from Brexton’s special day. "11 years of loving you, cheering you on, and trying to figure out how you grew up this fast," she captioned an Instagram post. "Happy birthday to my sweet boy. Watching you become this driven, funny, kind-hearted little man has been the greatest gift. So proud of you every single day, Brex."
From a young age, Brexton had been known to follow in his father’s footsteps. In October 2023, his mom and dad uploaded a joint Instagram post after Brexton had won a race at Millbridge Speedway. "Congrats Brexton, we are so proud of you!" they wrote. "For being so young, you put in so much effort watching film, testing, asking questions, siming, and it’s paid off! We love to watch you accomplish your dreams!"
On May 10th, Kyle also marked Lennix’s 4th birthday and Mother’s Day with a thoughtful Instagram post. "My girls deserve the spotlight today," he began alongside a photo of the family of four posing together. "Happy Mother’s Day to Samantha and my Mom! Thank You both for the love, patience, strength, and everything you pour into our family every single day." He added, "And Happy Birthday to our crazy Lennix. You keep us laughing, keep us on our toes, and somehow make every day brighter at the same time. I’m lucky to do life with you girls. Love you all more than you know!!!"
The nature of Kyle’s "severe illness" was not disclosed by his family on Thursday, but his death came hours after the announcement. "On behalf of the Busch family, everyone at Richard Childress Racing and all of NASCAR, we are devastated to announce the sudden and tragic passing of Kyle Busch," read a joint statement from NASCAR, the Busch family, and Richard Childress Racing.
