The 48-year-old singer had one last sing-a-long with daughter Maggie on Tuesday on their way to drop her off at college.
In an Instagram post, Hill belted out the tune to “Bad Blood” with her daughter, who held up the camera.
Driving with the windows rolled down, the video also showed a car stuffed with college essentials such as a pillow and luggage.
The mother-daughter duo seemed to know the words to Swift’s smash hit by heart.
In an interview with Country Countdown USA, Tim McGraw, Maggie’s father, said his daughter was interested in studying marine biology.
“She’s always been interested in the ocean, so her primary interest is marine biology,” he said. “She’s just about to start college, and we’ll see where it takes her. But that’s always been her biggest interest.”
The couple has not disclosed where their daughter will be studying. They have two other girls – Gracie, 19, and Audrey, 14.
