What Did Kyle Busch’s Wife Promise Him Before He Died?

Samantha’s post reveals a glimpse into her family life with Kyle Busch and their two children, 11-year-old son Brexton and 4-year-old daughter Lennix. She says that Brexton’s love for racing wasn’t forced on him, but rather something he and his famous father shared.

“They spent countless hours talking about race cars, working together, dreaming together, and building a bond around something they both genuinely loved,” she writes.

“Racing is what lights Brexton up and as long as it’s the dream in his heart, I’ll be right here beside him, cheering him on every step of the way,” Samantha continued. “And if one day his dreams take him somewhere else, that’s okay too.”

Samantha also said that dream is open to her young daughter, saying that she and Kyle recently bought Lennix her first kart for her fourth birthday last month.

What Was It Like For Samantha Busch to Watch Brexton Compete in His First Race Since Kyle Busch Died?

Samantha says that watching Busch compete in his first race since losing his dad was “both heartbreaking and beautiful all at once.”

“There are moments when I catch a glimpse of Kyle in him, the same determination, the same passion, the same spark, and for a second it feels like a piece of him is still right here with us. Those moments are incredibly hard,” she writes, but they also remind me that Kyle’s story isn’t over.”

She also said that, while being at the racetrack makes Kyle’s absence painfully clear, it’s also the place “where we feel closest to him.”

“So, we race on,” Samantha concluded.
