With lyrics like “You better respect your Mama,” mothers everywhere would be proud of their sons singing Tim McGraw and Faith Hill’s new duet, “Speak to a Girl.” And that list of proud mamas now includes McGraw’s sister, who recently filmed her son singing the tune. Tim then shared the video of his nephew belting out the tune on Instagram, along with the caption, “My sister caught my nephew singing along #SpeakToAGirl.”
