Tim McGraw shared a very rare photo of his half-brother Mark on Wednesday (June 13th).

The country music and 1883 star shared his pride after Mark successfully graduated from the Philadelphia Fire Academy, posting a photo of him posing in a blue uniform with a huge smile on his face.

“Congrats to my brother Mark and the entire 199th Cadet Class on graduating from the Philly Fire Academy! Good luck, be safe, and enjoy the celebration,” McGraw captioned the post below.

Tim’s father, former New York Mets and Philadelphia Phillies player Tug McGraw, gave him Mark, Matthew, and Cari as half-siblings.
