The 53-year-old singer hosted a gathering at her Mayfair home with celebrities including George Michael and Stella McCartney as guests.
However local residents called out the noise abatement team over her loud bash, reported Daily Mirror online.
One nearby dweller said that 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. She is a pain," a source 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. 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," he said.
