The couple which wed onstage at the Academy of Country Music Awards last year (12) is planning to name their unborn daughter Martina after the singer who performed the pair's marriage anthem. Martina McBride teamed up with Train star Pat Monahan to serenade Christina Davidson and Frank Tucci with the song Marry Me and the newlyweds have revealed they plan to honour the country star by naming their firstborn child after her. Pregnant Davidson revealed the news in a tweet on Thursday (01Aug13), writing, "We're expecting a baby girl! We're naming her Martina." McBride responded almost immediately and congratulated the couple on the baby news. The baby is due on 12 September (13).
