If you’ve been scrolling through TikTok lately, you’ve probably seen the San Francisco 49ers’ star defensive end, Nick Bosa, doing something other than crushing quarterbacks. He’s been making coffee. Specifically, espresso. But it wasn’t the caffeine that had everyone talking—it was the mystery woman frequently appearing in the background of his "coffee journey" videos.
For months, the internet was convinced Bosa was dating country music star Megan Moroney. It made sense on paper. Moroney was spotted at 49ers games, and the "Tennessee Orange" singer seemed like exactly the kind of high-profile match fans love to obsess over. But honestly? They were way off.
The real answer to who is Nick Bosa dating is a 20-year-old TikTok model and entrepreneur named Ella Ailiff.
The "Hard Launch" That Ended the Speculation
Nick Bosa isn't exactly a guy who loves the spotlight when he’s off the field. He famously called himself a "hermit" during a 2023 press conference, saying his post-practice routine basically consists of sitting on the couch with a Game Ready ice machine on his legs and going to bed by 8:30 PM.
That’s why the "hard launch" on November 30, 2025, caught everyone off guard.
Bosa posted a video titled "Coffee and football Sunday." In it, he’s not just brewing espresso; he’s sharing it with Ailiff. The clip showed them laughing, exchanging sweet kisses, and looking very much like a couple that has been together for a while. If you check his TikTok followers, she is actually the only account he follows. That’s about as "official" as it gets in 2026.

Who is Ella Ailiff?
So, who is she? Beyond the TikTok fame, Ailiff has her own thing going on.
- The Business: She’s the founder of a brand called Bella Blue Matcha.
- The Look: She’s a blonde model with a massive following (over 140,000 on TikTok alone).
- The Connection: Fans actually started piecing this together back in July 2025. Super-sleuths noticed her on Bosa’s boat and spotted her wearing his merch in the background of her own videos.
It’s a matcha-made-in-heaven situation, considering Bosa’s obsession with his @bosabearbrew coffee series. She makes the matcha, he makes the espresso, and they both apparently spend a lot of time "hermiting" together while Bosa recovers from his recent ACL injury.
What Happened to Lauren Maenner?
Before Ailiff, the name most associated with Bosa was Lauren Maenner. That relationship was a bit of a saga for 49ers fans. It was actually Bosa’s mom, Cheryl Bosa, who confirmed that one. In late 2023, she posted a photo of Lauren and the girlfriend of Nick’s brother, Joey Bosa, with the caption, “I love my sons gfs!!!”
Maenner, a model based in LA, was a staple at games for nearly two seasons. However, the two quietly split sometime in late 2024 or early 2025. There was no big dramatic announcement. They just stopped appearing in each other’s orbits. By the time the 2025 season rolled around, Bosa was back to his "hermit" ways—at least until Ella appeared.
The Megan Moroney "Curveball"
We have to talk about the Megan Moroney rumors because they were everywhere.
The country singer was spotted in a suite at Levi’s Stadium, and the rumor mill went into overdrive. People were analyzing her lyrics, looking for hints of a defensive end in her songs. Moroney finally had to shut it down herself. In an interview with People, she flat-out said she was too busy to date anyone.
Basically, the internet saw two famous people in the same building and decided they were getting married. It happens.
Why This Relationship Feels Different
Right now, Bosa is in a tough spot professionally. He suffered a torn ACL in Week 3 of the 2025 season—his third major knee injury. For an elite edge rusher, that’s a brutal mountain to climb.
While he’s been sidelined, Ailiff has been a constant presence. On January 6, 2026, she posted a wholesome photo collage on her Instagram story showing the two of them around the Bay Area. It wasn’t a "look at us" celebrity post; it felt more like a "supporting my partner through rehab" post.
The "Basement" Comment
Interestingly, Ailiff already has a sense of humor about the NFL spotlight. After the hard launch, some fans made jokes about her always being in Bosa’s house. She jokingly commented on her own post, "I'm not in his basement before anyone comments about that."
It’s that kind of self-aware, Gen Z energy that seems to balance out Bosa’s more reserved, old-school personality.
If you’re trying to keep up with the Bosa-Ailiff timeline, here’s what you should do next:
Keep an eye on the @bosabearbrew TikTok account. While Bosa is usually private, his "coffee journey" has become the primary way he shares his personal life. If you see a green matcha drink replacing the usual brown espresso, you'll know exactly who's behind the camera. Also, Ailiff’s brand, Bella Blue Matcha, is where she spends most of her time, so her business updates often double as life updates for the couple.
