Sienna Miller, who lives in Marylebone in north-west London, is infuriating other residents with her wild bashes which last till morning. The parties are so big Sienna has even started hiring her own security team to control revelers.
One angry neighbor told Britain's Independent newspaper: "She has parties with security guards outside that sometimes last until daylight. The music is so loud that it rattles our windows. When some one has gone round to complain, the music is turned down a bit and then turned up when they've gone. We're going to call the noise police if it carries on."
The parties have briefly stopped because Sienna is currently in Wales shooting new Dylan Thomas biopic 'The Edge of Love' - previously known as 'The Best Time of Our Lives'.
But her exasperated neighbors are dreading her return because they are convinced the noisy bashes will start up again.
The source added: "I'm not looking forward to her (Sienna Miller) coming back because the music will start up again."
