Martina McBride is embarking on a holiday tour for a third consecutive year. Tour dates have not been announced, but McBride tells CMT Radio she plans to take the show to four or five cities she's missed during her previous holiday tours. During earlier tours, McBride has featured her two young daughters, Delaney and Emma, and she's hoping to get Emma to sing. "She has lost one front tooth," McBride said, "and she's getting ready to lose the other one, so I thought maybe she could sing 'All I Want for Christmas Is My Two Front Teeth.' But I don't think that's going to happen. She's kind of shy about it." McBride's holiday shows will begin after her tour with Alan Jackson ends on Nov. 20.
