Beyonce & Nicki Minaj Have An "Ice Grill" Face-Off

We figured Beyonce and Nicki Minaj may have had a pretty good time rehearsing for their Tidal X performance of "Feelin' Myself," and now we have proof in a new behind-the-scenes clip. The choreography for the song ended with Bey and Nicki in a heated staredown, which seems to have been one of the most difficult parts of the routine for them.

In the clip, we see Bey challenge Nicki to giver her best "ice grill" and see who cracks first. Neither of the ladies seem to be able to hold it together for long. Guess it's easy to get star-struck even when you're a celebrity.
