Tim McGraw is beating the summer heat by shaving his head - and fans are freaking out over his shocking transformation. The country singer, 58, was photographed earlier this week heading to the studio in Nashville to work on new music. While fans can't wait to hear what McGraw is cooking up in his latest jam session, it's his physical appearance that is turning heads. McGraw debuted a bald head during the outing, which made his toned neck and ripped arm muscles even more evident, as seen in photos obtained by Us Weekly.
