Kelly Rowland said she was confused over why a run-in with Jay-Z sent the internet into a frenzy earlier this week.

Rowland and Jay-Z, who are both longtime friends, had a friendly encounter on the red carpet premiere for The Harder They Fall. The brief exchange was captured on camera, and eventually went viral. Jay-Z’s facial reaction to seeing Rowland soon became a meme, much to the confusion of Rowland herself.

“Some things I will never understand,” Rowland said when a fan asked her about the encounter during a recent Instagram live stream. “Like, I see my big bro all the time, but I guess you guys never see what we see? I don’t know.”
