The 40-year-old British catwalk queen, who was celebrating at China Tang restaurant, attended by 30 friends including Stella McCartney and Nick Grimshaw, caused complaints because of loud singing, reported Contactmusic.
"We nearly went to a karaoke bar but decided to have a sophisticated meal here instead. But we might as well have gone to the bar as this place feels just like one," a diner said.
"We're having to shout over the singing in order to hold a conversation. It's ridiculous," he said.
