When Kyle Busch became a father, NASCAR fans noticed a shift. The aggressive, hard-nosed “Rowdy” on track started showing a softer, gentler side of himself. And much of that change is credited to the smallest member of the Busch family—Lennix Key Busch. Since her birth in May 2022, Busch has gone from checkered flags to tea parties, from pit lane pressure to bedtime giggles. While he still chases wins on Sundays, it’s Lennix who’s been winning his heart every day.
Rowdy’s daughter has not only made appearances at tracks but has also taken over the spotlight in ways nobody expected. One moment, she’s feeding a kangaroo at Champion Ranch; the next, she’s applying glitter makeup to her dad’s face. Her charm has softened even the sharpest of critics. NASCAR fans have watched Busch hold purses at prayer sessions, model glittery blush without flinching, and cheer on his daughter’s every move.
It’s a new chapter for the two-time Cup Series champ, and it’s beautifully chaotic. Now, time has flown by, and that tiny girl who once clung to her dad’s leg at the track just turned three. Kyle Busch marked the moment with a birthday message that touched hearts across the NASCAR world. Notably, May isn’t just another month in the Busch household, it’s birthday central. Kyle celebrated his 40th birthday last week with a family vacation in Cabo. This week, it’s Lennix’s turn, and next up is Brexton, who celebrates his birthday on May 18.
For the Busch family, May is all about cake, memories, and heartfelt reflections. To celebrate Lennix’s special day, on Saturday, Kyle Busch shared an emotional post online. “Happy 3rd Birthday, Lennix! Can’t believe how much you’ve grown this past year! It’s unbelievable how smart you are! I’m ready for our next tea party and make-up night! Mommy and me love you so much!” he wrote, alongside a carousel of adorable pictures. The post, shared on X (formerly Twitter), was flooded with adorable messages and wishes.
The post gave fans another chance to witness the sweet bond between Kyle and Lennix. Busch, who’s yet to win a Cup race this season, has found victory in fatherhood. Since her birth via surrogate, Lennix has been a bright light in the Busch family, who have spoken openly about their struggles with infertility. That makes every birthday and milestone even more meaningful, and Kyle’s message reflected just that.

One fan perfectly summed it up: “Damn good race car driver but more importantly a championship dad.” And they’re not wrong. Kyle Busch has 63 Cup Series wins and two championships. But what people are talking about now is his track record as a dad. He’s been present, playful, and proud, qualities not often seen in the intense world of motorsports. Meanwhile, over the past year, Lennix has grown into a bold, witty personality. Her growing fan base now rivals some Cup Series rookies. Thanks to her mom, Samantha’s Instagram stories, the world has seen Lennix’s adventures, from playground antics to pit lane strolls.
It’s rare for a child to grab this much attention in the NASCAR world, but Lennix manages to do it with flair. Just last week, Lennix was seen holding a candy-colored teddy bear and proudly naming it “Chase Elliott.” The moment, captured in a video by Samantha Busch, showed the toddler’s enduring admiration for the Hendrick Motorsports driver. “When your daughter’s birthday wish is to meet her ‘boyfriend,’” Samantha captioned.
But her best birthday gift came from Chase Elliott at Texas Motor Speedway. The NASCAR Most Popular Driver met Lennix, who once called him her boyfriend, and had a beautiful conversation. Chase knelt down to greet Lennix, offered a high-five, and asked her age. She shyly responded with a tiny “two” gesture. This interaction followed her dream of watching Frozen with Elliott. It was a full-circle moment.
NASCAR Fans Show Up for Lennix!
The response to Kyle Busch’s birthday tribute to Lennix was nothing short of heartwarming. Fans from all walks of life came together to celebrate the little girl who’s quickly become a fan favorite, and they had plenty to say. One fan wrote, “Wow, it’s been three years. Time is flying, and Lennix is cute as a button.” The comment spoke to how quickly Lennix has grown, from a baby carried around the paddock to a young personality with a teddy bear named after NASCAR’s most popular driver. It’s a testament to how the NASCAR community has watched her grow in real-time.
“Happy birthday, Lennix, hope you got all kinds of Chase Elliott stuff for your birthday,” one fan joked. They can’t get enough of her playful crush. From teddy bears to in-person meetings, her Chase Elliott obsession has made her an even bigger hit with fans. “She is remarkable — so smart. Happy Birthday & we love watching you grow up. Stay sweet & feisty,” read another comment. The use of “feisty” matches Lennix’s growing reputation. Whether she’s cheering on her brother Brexton or hatching plans to join the racing ranks herself, fans see her as a spirited and bright young girl.
Finally, one fan offered a heartfelt reminder to Kyle: “It goes FAST, Kyle. Cherish it now as I wish I knew how much I’d miss it when they were on their own.” The wisdom in that comment struck a chord. It served as a gentle reminder that while races come and go, these moments with family are fleeting and priceless. These fan reactions show that the NASCAR world isn’t just about speed and trophies, it’s about family, shared memories, and real human connection.
Lennix may be only three years old, but she’s already left a lasting mark on fans and the NASCAR community. And with a dad like Kyle Busch cheering her on, there’s no telling how far she’ll go on or off the track. So, to the little princess of the NASCAR world, we wish a very happy 3rd and hope your day is full of giggles, cake, and love!
