On the inside of that same tattooed arm he has a image of an eye, which he said was a nod to his mother always watching over him. His most recent ink job is a bible verse on his right shoulder blade and he reportedly has a total of 20 tattoos. He is currently on his Believe world tour and his manager said he will release a new 3-D documentary very soon. His last album, Believe Acoustic, was released in January 2013. In September he was in China performing and during his time off stage, he was photographed being carried by two bodyguards up the Great Wall of China.
