William Byron’s girlfriend in 2026 is Kylan Darnell, a sports reporter, social media personality and former Miss Ohio Teen USA. The NASCAR Cup Series driver made his relationship with Darnell public in August 2026, attracting attention from racing fans. Since then, the couple have appeared together at major sporting events, including the US Open tennis tournament in New York. Before dating Darnell, Byron was romantically linked to Hailey McGregor and previously had a long-term relationship with Erin Blaney.
Who Is His Girlfriend?
Kylan Darnell is William Byron’s publicly known girlfriend as of November 2026.
The couple attracted attention after revealing their relationship during a break in the NASCAR racing schedule in August.
Darnell already had a public profile through her work in sports media, social media content and beauty pageants.
Their relationship brought together two people familiar with the demands of public attention.
Although Byron is best known for his achievements in stock car racing, Darnell has developed her own audience through digital platforms and sports-related coverage.
The couple have since been photographed together outside the NASCAR environment.
Who Is Kylan Darnell?
Kylan Darnell is an American media personality known for her social media presence, sports reporting and pageant background.
She gained wider recognition through TikTok, where her lifestyle and personal content attracted a substantial following.
Darnell is also a former Miss Ohio Teen USA, an achievement that helped establish her public profile.
Her experience in pageantry involved public appearances, interviews and participation in competitive events.
She later expanded her interests into digital media and sports-related work.
Her relationship with Byron introduced her to an additional audience of NASCAR supporters.
However, her career and online following existed independently of their romance.
When Did They Start Dating?
William Byron and Kylan Darnell publicly revealed their relationship in August 2026.
The announcement came during a NASCAR off-week, when Byron had a temporary break from his racing commitments.
Their appearance together quickly attracted interest among fans who follow the driver’s personal life.
Before that announcement, the exact date when they began dating had not been publicly established.
Going public with a relationship does not necessarily mean a couple started dating at that time.
For this reason, August 2026 is best understood as the period when their romance became publicly known.
Neither has provided a detailed public timeline of their earliest meetings.
US Open Appearance
One of the couple’s notable public appearances came at the 2026 US Open tennis tournament in New York.
Byron and Darnell were spotted together during the quarterfinal stage of the competition.
Their attendance attracted attention because it showed them spending time together away from NASCAR events.
The appearance also reflected their shared interest in professional sports.
For Byron, attending a major tennis tournament offered a change from the demanding atmosphere of stock car racing.
For Darnell, whose public career includes sports media, the event was another opportunity to engage with a major sporting occasion.
Their appearance reinforced public awareness of the relationship.
Is William Byron Married?
William Byron is not publicly known to be married as of November 2026.
His relationship with Kylan Darnell has been described as dating rather than marriage.
There has been no verified public announcement that the couple are engaged or planning a wedding.
Although fans sometimes search for information about Byron’s wife, his publicly reported relationship status does not support describing Darnell as his spouse.
The couple have also kept many personal details private.
Their public appearances confirm that they have acknowledged their relationship, but they do not establish future marriage plans.
Who Is Hailey McGregor?
Before his relationship with Darnell, Byron was reportedly linked to Hailey McGregor.
Online discussions associated the two beginning in late 2024, with references continuing into the 2025 NASCAR season.
However, comparatively little verified information is available about the nature and duration of that relationship.
Neither the precise beginning nor the end of their reported romance has been firmly established through the information provided.
As a result, McGregor is best described as someone Byron was previously linked to rather than assigning an unsupported relationship timeline.
The speculation attracted attention among fans who followed his personal life after his separation from Erin Blaney.
Relationship With Erin Blaney
Erin Blaney was William Byron’s most widely known long-term girlfriend before Kylan Darnell.
The couple reportedly began dating in October 2019.
Erin is the sister of NASCAR Cup Series driver Ryan Blaney, making the relationship especially interesting to racing supporters.
Byron and Erin were together for several years while both remained connected to the NASCAR community.
Their relationship attracted attention because Byron and Ryan Blaney competed against each other on the track.
Despite the professional rivalry, the personal connection between the families was widely discussed.
Why Did They Split?
William Byron and Erin Blaney reportedly ended their relationship in spring 2024.
Their separation was described as amicable.
Neither publicly established a detailed explanation for the breakup in the information available.
The couple had spent several years together, but their relationship eventually came to an end.
Following the separation, Byron continued focusing on his NASCAR career.
Erin also maintained her own personal life away from the attention surrounding the relationship.
There is no reliable basis for attributing their breakup to a specific disagreement or outside influence.
