Britney Spears files police report after altercation with security for NBA rookie Victor Wembanyama

San Antonio Spurs rookie Victor Wembanyama said Thursday he believes Britney Spears grabbed him from behind as he was walking into a restaurant at a Las Vegas casino, and that the security detail he was with pushed the pop star away.

Spears said, "His security then back handed me in the face without looking back, in front of a crowd. Nearly knocking me down and causing my glasses off my face."

Police said a report was filed on an incident at the Aria Resort & Casino, but gave no further details.

Spears' attorney Mathew Rosengart declined comment, citing the police investigation.

"I couldn't stop. That person was
