Justin Bieber insists he had the "right papers" when his pet monkey was confiscated by customs officers. The 21-year-old singer refused to listen to all his advisors who told him not to take OG Mally - an unexpected birthday gift - with him to Germany in March 2013, only for the creature to be seized and placed under quarantine shortly after he arrived in Munich. However, Justin insists he hadn't done anything wrong. He told America's GQ magazine: "Honestly, everyone told me not to bring the monkey. Everybody. "Everyone told me not to bring the monkey. I was like, 'It's gonna be fine, guys!' It was the farthest thing from fine. "In Germany, that monkey's endangered or something ... but I had the papers. "I even had it written out that he was a circus monkey and he could travel and all that s**t. I had all the right papers. Things get twisted." Justin was given until May 7 2013 to produce the proper paperwork for the capuchin monkey, but after he failed to respond, German officials demanded $8,000 to cover the cost of relocating OG Mally to a zoo, and the creature now lives at the Serengeti Park in Copenhagen. The 'What Do You Mean?' singer insists he has learned his lesson and would do things differently if he was ever given another pet monkey. Asked what he'd change if he got another, he vowed: "I'm not gonna bring him to Germany or travel with it anymore. "People are always like, 'Why did you get a monkey?' If you could get a monkey, well, you would get a f***ing monkey, too! Monkeys are awesome."
