When the Buffalo Bills are on a tear, the cameras usually pan to the luxury boxes. For years, those cameras found Brittany Williams, the woman everyone assumed was the future Mrs. Allen. They had the kind of story that Hollywood writers usually reject for being too cliché: childhood sweethearts from Fresno who stayed together through the grind of junior college, the jump to Wyoming, and the eventual $258 million NFL superstorship.
But then, in early 2023, the script flipped. Suddenly, the unfollows happened. The photos disappeared. And just like that, the woman who had been by Josh’s side for nearly a decade was no longer in the picture.
If you've been following the Bills or just browsing through celebrity news lately, you know that Josh Allen’s ex-girlfriend has become a topic of massive fascination. People aren't just curious about the breakup; they want to know how someone pivots after ten years of building a life around a franchise quarterback. Honestly, the way she’s handled the transition into her "New York era" is a lot more interesting than the typical "scorned ex" narrative.
The Long Road from Fresno to Buffalo
Most people think they just met in college. That's actually wrong. Brittany and Josh go way back to when they were eight years old. They grew up in the same California circles; her dad, Chris Williams, was a linebacker at Fresno State, so the athletic DNA was there from the start.
Brittany actually told a story on Kelly Stafford’s The Morning After podcast about a birthday party for Josh’s brother. A baseball flew over a fence, Josh grabbed it, and he gave it to her. She was eight. He was probably just being a kid, but she remembers feeling "embarrassed" because of cooties.
They didn't really "date" then, obviously. That came later. After a high school dance where Josh reportedly ghosted her—which is wild to think about now—they finally got serious in 2017. She was a cheerleader at Fresno State; he was slinging the ball at Wyoming. When he got drafted 7th overall in 2018, she was the one sitting right there.

For the next six years, they were the "it" couple of Western New York. They built a massive house together in Buffalo. They got a dog named Sky. They were a fixture. But as many fans noticed, despite the length of the relationship, there was never a ring.
What Really Happened with Brittany Williams?
The breakup wasn't a big press release. It was a slow burn of digital clues. In April 2023, fans noticed Brittany unfollowed Josh on Instagram. Then came the birthday trip to Rome where he was nowhere to be found.
Rumors flew. Some people whispered about "cheating," others said they just grew apart. Neither has ever come out and said, "This is why we ended." But Brittany did drop some heavy hints during an appearance on the Martinis & Bikinis podcast. She mentioned that being back in the dating world after ten years was "very, very, very difficult."
"I never thought I would be here again," she admitted.

The timing was definitely a gut punch for her. Within weeks of the split being "internet official," Josh was spotted in New York City with actress Hailee Steinfeld. To go from a ten-year relationship to seeing your ex with an Oscar-nominated star almost immediately? That's a lot for anyone to process.
The Instagram "Hacking" Incident
Things got a bit messy toward the end of 2024. After Josh and Hailee announced their engagement in November 2024, a comment appeared from Brittany’s account calling Josh a "brain-dead CTE athlete."
It went viral instantly.
Brittany later claimed her account was hacked and she was trying to get it resolved. Whether it was a hack or a moment of frustration, it highlighted the tension that still exists when a decade-long relationship ends so publicly. By the time Josh and Hailee tied the knot in May 2025, Brittany seemed to have shifted her focus entirely. She posted a photo of herself in NYC eating pizza with the caption, "I like this little life."
Life After the NFL Spotlight
So, what is she doing now? Brittany didn't just fade into the background. She moved to Manhattan and leaned hard into her own brand.
- Pilates by Britt: She’s a certified instructor and launched her own online fitness platform.
- Influencer Status: She’s been working with brands like Alo, Revolve, and Talentless.
- The "New" Dating Life: Recently, social media has been buzzing about her new relationship with a guy named Cooper James. It’s a very different vibe from the NFL world—more rodeo and outdoor lifestyle.
Why the Fans Are Still Invested
It’s easy to dismiss this as just another breakup, but for the Bills Mafia, Brittany was part of the family. She was close with the other WAGs, like Kyle Allen’s wife, Summer. When she disappeared from the sidelines, it felt like a shift in the team’s culture too.
The reality of being an NFL partner is that your identity often gets swallowed by the jersey number. Brittany has been vocal about reclaiming her own space. She’s described her current life in New York as her "Sex and the City moment."
Josh has clearly moved on—he’s married now and, as of early 2026, reports indicate he and Hailee are expecting their first child. The "Williams Era" is officially a closed chapter in his biography.
Lessons from the Split
If there's any takeaway from the saga of Josh Allen’s ex-girlfriend, it’s about the importance of building your own foundation. Brittany was with Josh before the money and the fame, but she also made sure to maintain her own career as a Pilates instructor and influencer.
When the relationship ended, she didn't lose her income or her platform.
For those following her journey, the best move is to look at her transition as a blueprint for post-breakup growth. She didn't stay in Buffalo. She didn't stop working. She moved to a new city, changed her circle, and leaned into her business.
