Justin Bieber's only gone and decided to add to his tattoo collection, this time with a tribute to himself.

Sitting just above his belly button, Biebs has had his (suspected)new album title 'Purpose' written in a nice arch across the middle of his abs.

While we're assuming it wasn't actually written backwards, and insteadlooks like that because of some front-facing camera handiwork.

Of course this isn't the first time JB has made his albums a permanent part of his skin, having previously had 'Believe' inked on his arm...

Just incase he forgets, maybe.
