Justin Bieber has become quite the collector ... of ink!
The 18-year-old pop superstar has added a new tattoo to his already plentiful array of permanent designs, this time inking a large "X" on his arm.
Photographers were the first to catch a glimpse of the "X" -- located on his arm next to the owl that he added last October -- on Monday night when the newly-single Bieber left a Cirque du Soleil show. Click here to see the new tattoo.
In addition to the owl, Bieber's other tattoos include a crown on the right side of his chest, "Believe" on his forearm, a praying hand on his leg, the Hebrew word for Jesus on his ribcage and an image of Jesus on his left calf, among others.
