Justin Bieber shirtless (again), gets a tattoo of his mom's eye

it's safe to say that Justin Bieber has more than a slight obsession with body art.

Since turning 16 three years ago, the teen heartthrob has amassed a whopping 16 tattoos.

But his latest inking, which he debuted on Instagram on Wednesday, is possibly the most bizarre yet.

The large artwork, which covers the entire width of the singer's arm and takes prominent pride of place in the crook of his left arm, is of his mother's eye!

'@bangbangnyc did this art ., Moms always watching ;)' he wrote in explanation of the pic.
Celebrity tattoo artist Keith 'Bang Bang' McCurdy, who is responsible for a number of Justin's inkings, including this latest one, is the go-to tattoo artist of Hollywood's A-list.

The tattoo was done just a day after the 19-year-old enjoyed a day of fun in the sun with a group of male pals as he took time out from his busy schedule on a friend's boat.
