Child star makes a massive comeback and leaves the judges in awe

Billy Gilman used to be a pretty big deal in country music, having multiple hit songs when he was only 12 years old. Like a lot of child stars, Billy found it hard to continue his career as he grew up.
Now he's back 16 years later and ready for a second shot. Taking The Voice stage by storm, Billy quickly made an impression on the judges. Miley and Blake even recognised him from all those years ago!
