Thousands of excited Directioners will pour into the London venue to see the boy band perform as part of their 'Where We Are' tour on Friday (6 June), Saturday and Sunday, and many have begun camping out nearby to ensure they get as close to the front as possible.
But if the eager fans are too loud in the lead up, they face been slapped with a Dispersal Order - which is usually used to control football hooligans.
Anyone asked by officials to leave the roads listed by the order cannot return for 24 hours and, if they ignore it and continue to cause a problem, they face being arrested, spending three months in prison and a £2,500 fine.
In a statement, Brent Police told ITV News London: "The concerts are a sell out and there are thousands of young females expected to turn up the night before the shows to camp out for the night in order to be first in line to get to the front of the stage.
"Some very loud screaming and singing may take place."
Best keep it down, girls!
