Jenner was on her way out of Breezy's Anaheim, CA, concert, which featured boyfriend Tyga and French Montana. The currently green haired teen was surrounded by security. However, you can see a hand come out of the crowd and grab a handful of her hair (or wig, who can say?) and hold on tight. Her head snaps back and you can see an expression of fear and shock on her face. Yikes! Fortunately, her security team jumped into action (now we understand why they're so aggressive, as can Jessica Alba), swatting the hand away and moving her along quickly. Here's hoping the rest of her night was less scary.
