Nick Bosa’s model girlfriend Ella Ailiff turned heads at Levi’s Stadium as she supported the 49ers during their 35-13 win over the Dolphins.
San Francisco 49ers star Nick Bosa had plenty to celebrate as his team secured a comfortable victory over the Miami Dolphins, but the defensive standout’s girlfriend also attracted plenty of attention on the sidelines.
Model and influencer Ella Ailiff was spotted at Levi’s Stadium as the 49ers played their first home game of the season following their opening-week trip to Australia.
The 49ers had begun their campaign with a victory over the Los Angeles Rams Down Under, but their return to San Francisco provided Bosa and his teammates with an opportunity to play in front of their home supporters.
San Francisco ultimately delivered another impressive performance, defeating the Dolphins 35-13.
While the result was the main focus for 49ers supporters, Ailiff’s appearance also became a talking point after she shared glimpses of her gameday experience online.
The 21-year-old model appeared in high spirits as she walked onto the field wearing a white top underneath a black vintage-style 49ers jacket.
She completed the look with sunglasses and a handbag, giving her gameday outfit a fashion-focused touch while showing her support for Bosa and the team.
Ailiff’s appearance came after she and Bosa made their relationship public in late 2025.
Since then, the couple have attracted interest from NFL fans and followers of the model, with Ailiff occasionally sharing content connected to her life away from the football field.
Her latest appearance at Levi’s Stadium gave fans another glimpse of the couple’s relationship while Bosa continued his season with the 49ers.
Ella Ailiff Supports Nick Bosa at Levi’s Stadium
The game against Miami was particularly notable because it appears to have been Ailiff’s first opportunity to watch Bosa play live this season.
The 49ers opened their campaign against the Rams in Australia, but Ailiff did not make the trip Down Under for the season opener.
That meant the Dolphins matchup represented a return to familiar surroundings for Bosa and an opportunity for Ailiff to watch him compete at Levi’s Stadium.
The defensive lineman has been working his way back after suffering an ACL injury last season.
Although Bosa had yet to record a sack in the early part of the season, he remained a disruptive presence for San Francisco’s defense and continued to create opportunities for teammates along the defensive front.
His ability to pressure opposing quarterbacks can also help create opportunities for other 49ers pass rushers, even when he does not appear in the statistics with a sack.
The 28-year-old remains one of the most recognizable defensive players on San Francisco’s roster.
Bosa and Ailiff Went Public With Their Romance
Bosa and Ailiff went public with their relationship in late 2025, bringing another chapter of the NFL star’s personal life into the spotlight.
Before dating Ailiff, Bosa had been linked to Megan Moroney, Jenna Alexa Berman and Madison Gestiotto.
Ailiff, meanwhile, has built her own following as a model and social media influencer.
She has more than 141,000 followers on TikTok and over 25,000 followers on Instagram, giving her a sizable audience beyond her connection to the NFL star.
Her social media presence includes fashion and lifestyle content, making her appearance at 49ers games a natural extension of the content that has helped her build her online following.
Her latest outfit also reflected that blend of sports and fashion, with the vintage-inspired 49ers jacket serving as the centerpiece of her gameday look.

The attention surrounding Ailiff came on a successful afternoon for the 49ers.
San Francisco ran out 35-13 winners against Miami, continuing their strong start after beating the Rams in Australia.
The victory gave the team another positive result as they returned to their home stadium, while Bosa continued to make an impact despite not yet registering a sack.
The defensive star’s return from his ACL injury remains an important storyline for San Francisco, with the team relying on his ability to disrupt opposing offenses.
For Ailiff, the game provided an opportunity to support Bosa in person and experience a 49ers home game.
She appeared to enjoy the occasion, smiling as she made her way onto the field in her team-inspired outfit.
With the NFL season now underway, Ailiff is likely to attract continued attention whenever she appears at Levi’s Stadium to support Bosa.
The model’s growing social media profile means her gameday appearances can generate interest of their own, while her relationship with one of the 49ers’ biggest stars gives fans another reason to follow her content.
For Bosa, however, the focus will remain on getting back to his best following last season’s ACL injury and helping San Francisco’s defense maintain its strong start.
And after a 35-13 victory over Miami, both Bosa and the 49ers had plenty to celebrate at Levi’s Stadium.
