Madonna's after-show party following a concert in London's Hyde Park caused neighbours to complain about noise pollution.
The 53-year-old singer threw the bash at her Mayfair home with George Michael and Stella McCartney, to the dismay of residents, who called out the noise abatement team over her loud music and screeching.
On Wednesday night a neighbour, who asked not to be named, claimed the council did nothing to stop the noise until it was too late.
"It went on until quarter past two. It was all out in the garden - it woke me up," the Mirror quoted a neighbour as saying. She is a pain," the neighbour said.
A Westminster Council spokesman said that a complaint about loud music was called in after midnight from a resident in Great Cumberland Place.
"When officers arrived, they could clearly hear music and shouting," spokesman said.
"In their opinion it was unreasonable on a weekday evening so they served a noise abatement notice on the owner of the house.
"As soon as the notice was received, the volume was turned down and there were no further complaints," the neighbour added. (ANI)
