Martina McBride has been asked to sing The National Anthem at the Steelers/Jets AFC Championship game this weekend in Pittsburgh. Sounds like a great choice, for two reasons: She always sings the Anthem great, and she's been a good luck charm for the Steelers this season. The team's marketing manager John Wodarek says, “Martina is 2-0 and we hope she brings the magic to stay undefeated.” Fans can tune in to CBS to see the performance broadcast live from Heinz Field this Sunday, Jan. 23 at 5:30PM CT.
