It seems that Jaden Smith isn't the only Smith to catch Justin Bieber's eye. J.B. wowed fans at his Los Angeles concert by bringing surprise guest Willow Smith on stage for an epic dance battle.

Fans at the Staples Center were screaming hysterically as the Whip My Hair singer and Biebs danced side-by-side to Cali Swag District's Teach Me How to Dougie. Both were excited to show off their wild moves.
