According to the Irish Independent, the Bieb has decided not to fight for his right to keep the critter -- which was seized because he didn't have the proper papers to bring the little guy into the country. Animal control officials criticized Justin for keeping the three-month-old monkey as a pet, since babies of that species normally stay with their moms for at least a year.

Justin had been given a deadline of May 17th to decide whether to return for Mally.
