Mariah Carey set to perform her iconic song, "All I Want for Christmas Is You," before the Kansas City Chiefs and Pittsburgh Steelers face off at 1 p.m. EST.

Beyoncé is teasing her highly anticipated performance during the Ravens and Texans NFL Christmas Day game, calling it "A Cowboy Carter Christmas."

Styled by costume designer Shiona Turini, Beyoncé wore a statement feather coat from Atelier Biser to create her all-white look. She completed the outfit with glossy pants, matching heels and a dramatic furry cowboy hat.
