Josh Allen and the Buffalo Bills are gearing up for the big divisional playoff game at the Denver Broncos on Saturday. During the week, his younger sister Makenna Allen celebrated her big birthday in style with a bold Bills fit.

The 29-year-old reigning MVP quarterback is trying to bring Buffalo home its first Super Bowl championship this season and will take all the fans cheering him on at loud Mile High Stadium in Denver on Saturday as he can.

While it remains to be seen if wife and actress Hailee Steinfeld will show up after skipping the Wild Card game for a selfish reason, his younger sister MaKenna will likely be there and was already in fine game-day form with her sparkly Bills look while celebrating her 25th with family.
