Jennifer Lopez took the time to reflect on all the preparation that went into her and Shakira’s Super Bowl LIV halftime show performance, which was somehow already three months ago. On Sunday, J-Lo took to Instagram to post some never-before-seen behind the scenes footage from their halftime show rehearsals.

“I can’t believe it’s already been 3 months since the #SuperBowlLIV #Halftime Show!” she wrote. “So much has happened since then, but I wanted to share a fun peek behind the scenes at our first rehearsal with the dancers and @Shakira.” In the post, she included a handful of videos of everyone rehearsing different parts of the performance, but it was one clip of her and Shakira in particular that caught people’s attention.

In the second-to-last video, J-Lo can be seen showing Shakira how to get her butt to jiggle to its full capability. “I do it with my knees, I shake my knees,” she tells the “Hips Don’t Lie” singer, demonstrating her ass-shaking technique. “If you shake your knees, your butt goes.” J-Lo then reveals where she learned this handy trick. “My mother taught me that,” she tells Shakira. “When I was four!”
