So much for fully embracing the NFL WAG lifestyle like Olivia Culpo, Hannah Ann Sluss, and Taylor Swift.

Yet, Maenner was at Sunday’s NFC Championship game, posting an Instagram story of Bosa’s pregame entrance and celebrating on the field with him after the win with the caption ‘my best friend!’

Bosa and Maenner were also spotted kissing on the field and clearly not hiding their relationship to the masses, despite not talking about it publicly.

So who is Maeneer and how long have her and Bosa been together?

Maenner is a 26-year-old model and public relations specialist who has been dating Bosa for over a year.

Speculation started that she was dating Bosa when she posted an Instagram photo with Nick’s mother, Cheryl Bosa. Also in the photo was Nick’s younger brother and Los Angeles Chargers’ star Joey Bosa’s girlfriend, Amanda Kassdikian, with the caption ‘“Chargers are the second favorite team ok.’

Cheryl Bosa herself confirmed her son’s romances last year with an Instagram photo of Maenner and Kassdikian with the caption ‘I love my sons gfs!!! #mamabearscublets.’

The only photo in a post on either Nick Bosa or Maenner’s Instagrams is from a carousel of photos she posted last year of the two hugging in a mirror’s reflection.

Maenner has more than 27,000 followers on Instagram, where her support for Bosa has mainly come through stories.

Bosa played in a Super Bowl during his rookie season, but on February 11, he will play in the NFL’s biggest game for first time with Maenner by his side.

Maenner is one of the 49ers NFL WAGs crew that includes Culpo, Mahogany Jones, Claire Kittle, and Kristin Juszczyk.
