Last week, Beyoncé and Nicki Minaj performed "Feeling Myself" together for the first time ever at Jay Z's Tidal benefit concert, and now Beyoncé has shared an adorable video of the pair rehearsing before the show. Apparently, the part at the end of the performance where they stared at each other until someone lost it was planned beforehand. 'Ice grill me as long as you can,' Beyoncé says in the clip. 'Let's have a contest. Let's see who cracks first. I have a feeling I'm gonna crack first.' Spoiler alert: She did! Why aren't all friendships this cool?
