The tot in this video is not a fan of Justin Bieber's famous haircut.  Go easy on him, Bieber fans. He's only three. 

While Ted enjoys Bieber's performance of "U Smile" (and displays some impressive pipes of his own), he has some harsh words about his new hairstyle. "His hair looks funny. It's so bad," the little guy says, cackling. Burn! That's some cold dinner, Ted. Watch the ultimate Bieber diss below.
