Val Chmerkovskiy Pranks Zendaya on Z100 Radio 2/12/14

Zendaya stopped through to chat with Garrett from Elvis Duran and the Z100 Morning Show. What she did not know was that Garrett devised a plan to prank her by having her "Dancing With The Stars" partner, Valentin Chmerkovskiy, call in and pretend to be her "biggest fan".
