Justin Bieber unveiled on Instagram this weekend his latest body art.

A brief Instagram video and photo of the 23-year-old singer snapping a selfie in a bathroom mirror show his torso completely covered in tattoos, including images of a bear, lion, eagle, cross and human skeleton.

"@justinbieber Thank you for the trust. 26 hours over 3 consecutive days is the most I've ever tattooed anyone in my 13 year career. You're tough as nails man!" reads a post on Bang Bang Tattoo's Instagram account.

The message accompanies a photo of Bieber -- seen from the back and standing near a hot tub.
