Running into your favourite celebrity is always exciting, however some people make it their hobby to stalk fans at airports, and sometimes it can turn a little ugly.
As celebrities have pointed out before, they're people too, and if they don't want to stop for a photo that's totally fair.
However, some fans don't accept that behaviour, and will lash out, like these ones did towards the girls of Fifth Harmony when they didn't stop for photos.
Instead of accepting it, the fans started yelling things out like "Camila [Cabello] would never!" and "Camila would stop for photos!"
Not only that, but they started following the girls and singing Camila's hit single, "Havana".
Harmonizers quickly jumped online and started defending the fandom, calling out the group of people at the airport 'not real fans'.
But Camila fans even got involved, saying they would never support that behaviour either.
It's important to remember respect when meeting a celebrity, because this kind of behaviour isn't just rude, it's harassment.
