As she touches his shoulder, without turning or looking back the security guard backhands her. It is unclear whether he actually hits her or hits her hand which is pushed back onto her face.
However, as per the Las Vegas Police Department, Britney Spears had been the one to hit herself in the face after Wembayama's security guard pushed her hand off. And some members of Spears' security team said that the singer was not hit with a closed fist and that the guard had pushed the hand off without looking at whose it was.
Either way, he face is struck and she cries out, "That's America for you. F*** you all!" in a British accent.
A spokesperson for the Las Vegas Metropolitan Police Department said that no charges would be pressed against the security guard.
