Josh Allen's girlfriend is proud of her man despite the loss on Sunday -- saying the Bills quarterback is a "true leader," especially after everything the team went through this season.
Brittany Williams -- who started dating Allen in 2015 -- published a sweet note to her Instagram page on Monday ... a day after the Bills' 27-10 loss to the Cincinnati Bengals.
"So proud of this man," the 25-year-old said. "You are the most amazing & selfless person I know."
"Through all the highs of this season and the many many trials of adversity your team faced, you remained the same & never wavered.
