When Victor Wembanyama learned that one of his security guards slapped Britney Spears, he thought he was being pranked.

Spears, 41, was reportedly slapped by the security guard when she was trying to get a photo with the No. 1 overall pick in the 2023 NBA Draft at Catch restaurant in the ARIA Hotel in Las Vegas.

“What happened last night, is, I saw the news obviously, I woke up to a couple phone calls — something did happen when I was walking with some security from the team to the restaurant. We were in the hall. There was a lot of people,” Wembanyama said told reporters Thursday at NBA Summer League in Vegas.

“There was one person who was calling me, but security told me I couldn’t stop because it would have made a crowd. That person grabbed me from behind. I didn’t see what happened because I was walking straight and didn’t stop, and that person grabbed me from behind, so I just let security push her away. I don’t know with how much force, though.

“Security pushed her away, and I didn’t stop to look. I kept walking and enjoyed a nice dinner.”

He was asked if he realized at the time that it was Spears.

“Actually, I didn’t know for a couple hours,” Wembanyama answered.

“When I got back to the hotel, I didn’t forget about this, but I thought it was no big deal. And then [I was told] this was Britney Spears. At first, I was like, ‘No, you’re joking!’ But yeah, it turns out it was Britney Spears.

“I never saw her face.”

According to TMZ, it was Damian Smith, the Spurs’ head of security, who slapped Spears.

After the incident, Spears reportedly “composed herself” as the security guard apologized and told her, “You understand how it is when you’re being swarmed by fans.”

Spears was said to have accepted the apology.
