Justin Bieber

Justin Bieber is always up to something and yesterday night (October 19) Justin Bieber gave a killer performance in Vancouver, Canada. The "One Less Lonely Girl" singer took the stage at the Rogers Arena and even had a little extra action for his many fans.

Justin showed off his Kung Fu skills by performing a choreographed fight sequence with his backup dancers, and his moves looked pretty impressive.

Speaking of fighting, it seems the boy who claims Justin roughed him up during a laser tag match has filed a formal complaint.
