Nick Bosa’s mom gushes over his model girlfriend Lauren Maenner attending the 49ers’ win over the Eagles in his No 97: ‘Representing!’

Nick Bosa's mother was thrilled to see his girlfriend Lauren Maenner represent the San Francisco 49ers defense during their win over the Philadelphia Eagles.

The 49ers earned a blowout victory over the Eagles at Lincoln Financial Field on Sunday, defeating last season's Super Bowl runners-up 42-19 and solidifying their status as one of this season's top contenders.

And there to watch it unfold in Philadelphia was Maenner, Bosa's model girlfriend, donning a top with his number 97 in the stands.

Maenner, who has 23,000 followers on Instagram, shared a series of photos of himself during Sunday's match on the platform – which certainly went down well with Bosa's mother.

Cheryl Bosa reposted one of the photos, in which Maenner appears to be wearing her son's number 97 under a jacket, to her story, writing, “Representative! Go 49ers!!!'

It turned out to be a successful trip to Philadelphia for the 49ers WAG, who watched her friend help San Francisco produce one of the performances of the season so far against Jalen Hurts and Co.

Bosa's mother first confirmed their relationship on October 25 by posting a photo of Maenner with Amanda Kassdikian, the girlfriend of her eldest son and LA Chargers linebacker Joey Bosa.

However, it is currently unclear how long the pair have been fully dating.

Cheryl also posted a photo with Maenner, who was wearing a denim jacket with “Bosa” on the back, at Levi's Stadium in early October when the 49ers defeated the Dallas Cowboys.

Bosa, an All-Pro defensive lineman, first became romantically involved with Maenner over the summer.

He reportedly appeared on her Instagram Story in July, a month before fans were convinced she shared a cozy photo with him.

Maenner is signed to Next Model Management in Miami, as well as The Industry in Los Angeles, and also has a bachelor's degree in public relations.
