Kate Moss, who recently celebrated turning 40 at the China Tang restaurant, has been ripped for upsetting fellow diners at the posh Mayfair establishment.

One of the diners told the Mirror that the sophisticated restaurant felt like a karaoke bar because the supermodel and her party mates, including Sadie Frost, Stella McCartney, John Galliano and her close pal Naomi Campbell, were singing at the top of their lungs.

The eyewitness asserted that people had to shout over the singing in order to hold a conversation, adding that it was ridiculous. The party people were heard singing songs by INXS, Rolling Stones and Fleetwood Mac and seen downing almost 40 bottles of Taittinger, which cost 130 pounds a bottle.
