Justin Bieber: I'm Adopting Another Primate ... Monkey Org Goes Ape

Justin Bieber has been called "foolish" and "irresponsible" by a monkey protection organization that is indignant over his vow to adopt another pet primate.

Bieber now says "monkeys are awesome" and he wants another one, with this proviso ... "Just gotta make sure I got a house and it stays in the f***ing house ... I'm not gonna bring him to Germany."

The Deutschland reference ... in 2013 he took his monkey, Mally, to Germany where customs officials confiscated it after Bieber didn't have the proper documents. He never tried retrieving it.

Now the North American Primate Sanctuary Alliance is lashing out, warning Biebs getting another primate "will prove dangerous to both you and your monkey, as well as irresponsible when it comes to your public following."

The org pleads, "Please do not repeat this foolish endeavor."

NAPSA wants the word out that monkeys carry disease and turn hostile when owners try to domesticate them, telling Bieber, "It is simply not possible to fulfill the unique needs of your monkey within a private home."

And that says it all.
