The country star got on her knees to sing face-to-face with Rosie, a native of Mississippi who sent Faith a video of herself performing the singer’s 2005 smash “Mississippi Girl.”

“You just made my day when I saw your little video. You’re precious,” Faith told Rosie before they sang the song that hit No. 1 before the young fan was even born.
