Justin Bieber doesn't just know the word "German" -- he can also speak it!
After video of him appearing confused as ever over the word on New Zealand TV made the rounds, an angry Bieber posted this old vid on his Twitter -- where he counts to 10 in the language and even translates his last name!
The Biebs also added "guess home schooling is working out. Do your research next time b4 making a lame attempt at hating on a 16 year old."
Duly noted.
