Fresh off his second career Daytona 500 victory, William Byron is making headlines again—this time, not for his skills on the racetrack, but for his activity on social media. The Hendrick Motorsports driver was spotted commenting under pop star Sabrina Carpenter’s latest post, sending fans from both worlds into a frenzy.

Byron’s Unexpected Cameo in Carpenter’s Comments
Sabrina Carpenter, known for her chart-topping hits and viral presence, recently posted a new photo that quickly grabbed attention. While celebrities and fans alike flooded the comment section, one reply stood out—none other than William Byron, the NASCAR star who just conquered the Great American Race for the second time.
Byron’s comment, which was accompanied by a couple of grinning emojis 😅😅, immediately caught the attention of his followers. While it wasn’t anything overly flirty or dramatic, it was enough to spark speculation and amusement from NASCAR fans, many of whom didn’t expect to see the 26-year-old driver engaging with a pop sensation.
Fans React: “Byron’s Got That Winner’s Confidence!”
As soon as Byron’s comment appeared, fans wasted no time reacting. Some playfully suggested that winning two Daytona 500s has given Byron a new level of confidence, while others joked that he was simply shooting his shot.
“Back-to-back Daytona wins and now this? William Byron is unstoppable,” one fan quipped.
“Bro just won the Great American Race and now he’s going for the Great American Pop Star,” another joked.
Others pointed out that this isn’t the first time NASCAR drivers have shown appreciation for celebrities on social media. From Kyle Busch interacting with musicians to Chase Elliott liking viral posts, the crossover between NASCAR and pop culture is becoming more common.
Byron’s Social Media Presence Growing Post-Daytona Win
Since his victory at Daytona International Speedway, Byron’s social media following has skyrocketed. His win marked Hendrick Motorsports’ 9th Daytona 500 victory, and as a two-time winner, he’s quickly solidifying himself as one of NASCAR’s biggest stars.

While his comment under Carpenter’s post may have been harmless fun, it’s a sign that Byron is enjoying his moment in the spotlight. Whether or not there’s anything more to it remains to be seen—but for now, it’s safe to say that William Byron is winning both on and off the track.
