Nicki Minaj and Beyoncé teamed up for a show-stopping performance [3] at the Tidal X: 1020 concert [4] last week, and now the world is getting a look at how it all came together. On Monday, Beyoncé released a short behind-the-scenes video of her and Nicki having a staring contest while rehearsing for the big show, and the caption reads, "Let's see who cracks first . . ." In the clip, which is appropriately titled "Ice Grill," Beyoncé tells Nicki, "By the way, ice grill me as long as you can. Let's have a contest." To see who won, watch the video above, then check out how Beyoncé kick-started Halloween [5] a week early.
