Country Stars' No. 1 Fans: Their Mamas

Blake, Carrie, Alan – these superstars are never too big celebrate mom

CARRIE UNDERWOOD

Underwood wrote her 2009 hit "Mama's Song" in honor of her own mom Carole, an Oklahoma elementary school teacher who appears in the song's music video. While the tune tells the story of a woman moving away from home to start her own life, Underwood's mother is never too far away, joining her in Las Vegas at the ACM awards in April.
