Say what!? Justin Bieber was at the zoo the other day taking to the pandas..and he seems to think they listen to his music.

A witness claims that JUSTIN BIEBER was talking to the pandas at Zoo Atlanta on Monday.  She says he was saying things like, quote, "I know you've listened to my music" and "Wake up, panda I know you wanna take a picture with me."  He was also being obnoxious and kicking the glass.

Speaking of talking to animals...that reminded us of this...LOL
