Tim McGraw was spotted in Nashville this week sporting a newly shaved head and showing off his muscular physique as he returns to the recording studio – as well as the gym – following recent back surgery. The 58-year-old country star previously had to withdraw from his scheduled performance at the Last Cowboy Standing event on July 21 due to his ongoing recovery. Back on July 1, McGraw shared an affectionate Instagram post with his wife, Faith Hill, while they were in Copenhagen to support their daughter, Audrey McGraw, who was opening for Brandi Carlile on her Lost In Time Tour in Europe. McGraw is now preparing to headline a pregame concert at the MLB Speedway Classic in Bristol, Tennessee, on August 2, alongside Pitbull and Jake Owen. (People)
