Justin Bieber added some new ink to his already inked up body.

The singer showed off his new body art over the weekend, tweeting a photo of a brand new owl tattoo on his left forearm.

The tatt is right next to his "Believe" tattoo ... and is the 8th piece on his body.

Justin has gotten 5 other tattoos in this year alone. He already has the aforementioned "Believe" tatt, a crown, a bird, Jesus, praying hands, Hebrew writing and a Japanese symbol meaning "music."

What do you think of his latest addition? Is it all too much for the 18-year-old ... who may soon look like Travis Barker if he keeps going at this rate!
