Beyoncé surprised fans by bringing out Shaboozey to perform "Sweet Honey Buckiin," and Post Malone joined her for "Levii's Jeans."

Beyoncé's performance will take place during the second of Netflix’s two Christmas Day games, when the Houston Texans host the Baltimore Ravens at NRG Stadium at 4:30 p.m. EST. The games will be broadcast live on Netflix. However, that isn't the only place to watch.

Mariah Carey is practically synonymous with Christmas at this point. So it should be no surprise she'd be a part of the NFL Christmas Gameday special.
