The 27-year-old was recently found dead at the London property and fans have been flocking there to pay tribute to the star and leave messages of condolence.
However some have been getting drunk and causing problems for neighbours and the police had to be called to keep them away from the properties.
One neighbour said to UK newspaper The Sun: 'People have been getting drunk on the square. If a fight broke out who knows what could happen?'
According to the newspaper, a member of security said: 'Things got a bit rowdy. People were blaring music out and drinking in the street.'
