Some accused the singer of wearing a dress that was too revealing.
Ciara sang the national anthem before the kick-off of Monday night's college football championship game between Alabama and Clemson.
For many, the problem wasn't Cici's rendition of the "Star Spangled Banner," it was her dress.
Bonnie Bernstein, a former ESPN sideline reporter, thought Ciara's choice of clothing was a little too revealing to wear during a nationally televised game.
FOX Sports personality Jason Whitlock echoed Bernstein's sentiments, tweeting in agreement.
But not all shared Bernstein and Whitlock's opinion.
And the most important person to side with Ciara's dress? Her boyfriend and Seattle Seahawks quarterback, Russell Wilson.
What do you think of the reaction to Ciara's dress?
