Britney Spears and NBA phenom Victor Wembanyama have critically different accounts of what went down before his security guard slapped her, and video of the incident, obtained by TMZ, supports Britney's version.
Check out the video ... you hear Britney approach Victor outside Catch restaurant in Vegas Wednesday night, screaming in a British accent, "Sir, Sir!"
Britney reaches up an taps Victor on his left shoulder. This is important because Victor described Britney "grabbing" him. The video does not support that claim.
