Kane Brown has photos to prove he “hasn’t changed a bit” over the years.

In an Instagram post, he said, “Smiling big since day one [crying laughing and red heart emojis],” sharing three photographs of himself as a baby.

The first showed him wearing a red and white outfit and smiling a big gummy smile. His bottom gums have two teeth, indicating he’s six to 12 months old.

In the following photo, Brown is seen wearing a white sailor shirt, blue diaper cover, and white cap.

In the final photo, he smiled pleasantly in his blue sports shirt. However, the 30-year-old had the same smile and face, exhibiting little change as he grew older.

Many noted his strong genes, saying his two children, Kodi and Kingsley favour him. One said they are “the perfect blend of you and your beautiful wife!”
