Turns out the Beeb's more hardcore than we thought!
The tween heartthrob was photographed a few weeks ago in Sydney with what looked like a small bird tattoo on his hip and guess what, it's not a rub-on!
Here's the photographic proof that the Beeb really did visit a tattoo parlour in Toronto, Canada, shortly before coming to Oz.
But don't you have to have your parent's permission to get a tatt if you're under 18? Justin's dad must be a pretty cool guy – Jeremy Bieber signed the permission forms and stood by to watch his son get inked for the very first time.
The bird is a Bieber family tradition - many members of the family have the same tattoo.
Now watch out, because half the teenage population world is going to want the Bieber bird tattoo... if their parents will let them.
