(BANG) -Kate Moss celebrated her birthday in style with a 24-hour party. The supermodel marked her 33rd birthday by spending more than £5,000 on a marathon drinking session in London on Tuesday (16.01.07).

Kate - who was sporting an identical ring to lover Pete Doherty on her right hand - began the celebrations in her Primrose Hill home where she drank champagne with friends.

After spending more than three hours getting ready, Kate left her house in skinny jeans and a cream coat to meet Pete at Scott's oyster bar in Mayfair. The couple dined on seafood and champagne, but Kate's meal was reportedly ruined when Pete refused to discuss their future together.

A source told Britain's Daily Star newspaper: "Kate wanted to discuss plans to buy a new family home in London. She is keen to have a brother or sister for her daughter Lila Grace. But Pete wants to go on wild romantic tour across America. He was also in a mood because he wanted sausage and chips, not oysters!"

Kate - who changed into a revealing cream dress and faux fur coat - then went to the Donmar Warehouse theatre to watch 'Don Juan In Soho', starring her close friend Rhys Ifans.

Celebrations then moved to the Dorchester Hotel's China Tang restaurant, where Kate drank £450 bottles of Cristal champagne with Pete, Sadie Frost, former Clash bassist Paul Simonon and TopShop owner Sir Philip Green.

As Kate's friends sang 'Happy Birthday' to her the blonde reportedly hitched up her cream dress - which was slashed to the thigh - and flashed her suspender belt.

Pete - who was due in court the next morning - left the party before midnight, but Kate was determined to continue celebrating.

The supermodel and her friends left the restaurant just before 3am - reportedly leaving the £2,400 drinks bill to be settled by owner David Tang.

Kate took the party back to her home, where they danced and drank tequila slammers until 10am. After a quick power nap, she embarked on a shopping trip before heading to a North London pub to continue partying.
