You would think that at a Lady Gaga concert, fans would want to just dance.
Not so on Tuesday night, when the singer found herself briefly stopping her own show in Washington, D.C., after an altercation broke out between two people near the front of the stage.
"Stop fighting. Do not fight at this show," she insisted, before inquiring: "Is she OK? Are they both OK? I don't know who hit who."
Sounds like a couple of Little Monsters got a little too monstrous.
