Britney Spears called the San Antonio Spurs’ Victor Wembanayama a liar in a Thursday Instagram post after the basketball phenom told reporters the pop singer grabbed him from behind before a member of his entourage slapped her at a Las Vegas restaurant. Spurs Director of Team Security Damian Smith reportedly backhanded Spears at the Catch restaurant Wednesday after she approached Wembanyama to snap a photo. The 5-foot-4 Spears initially said she tapped Wembanyama, who stands at 7-foot-3, on the shoulder while he was walking to his table.
