Justin Bieber commissioned celebrity tattoo artist “Bang Bang” McCurdy to ink his 19th tattoo – a large and very realistic-looking eye on the inside of his left arm, which the singer debuted on July 17, 2013. The eye tattoo on his arm is a tribute to his mother, Pattie Mallette. The tattoo took about 20 minutes.
