Fans will remember that Carrie and Ludacris teamed up in 2018 for the certified platinum song, "The Champion." Carrie shared a selfie with Ludacris and wrote, "Pretty sure @ludacris is the only person who could get me out to the club after my show @resortsworldlv. Fans rushed to the comments section to say, "Is that really Carrie Underwood?"
