Mally [Maul-ee] is Justin's capuchin monkey. Mally was named after a human man named Mally Mall, who gave him the monkey as a birthday present, because Bieber had always wanted one.
The monkey was only 14 weeks old when Justin had to leave him. Bieber's pet monkey was confiscated at a German airport in March 2013. German officials told him he had until May 7, 2013 to provide the correct documentation, and Mally would be returned. Justin missed the deadline, and Mally officially became German property.
Justin had the papers and had even written out that he was a circus monkey and he could travel.
