Kate hits the buffers - 34-hour party finishes after just 18

But Kate Moss didn't even make it out of her teens.

By the 18-hour mark - 8am yesterday - she had hit the pillow at her new £8million home in St John's Wood, North London.

Pictured arriving there as the rest of the city was leaving for work, the supermodel showed the strain of her night of excess.

The fact Miss Moss made it that long is admirable.

She had been going since at least 2.30pm on Wednesday at the Dorchester on Park Lane.

There, she had booked two top-floor suites for £2,500 each.

A friend said: "Kate was determined to go for it. She has been paranoid that everyone is saying she's too old and past it.

"She had already been knocking back the Dom Perignon by the time she left her house for the Dorchester."

Miss Moss and some of her closest girl friends - Davinia Taylor, Meg Mathews, Fran Cutler and Kelly Osbourne - enjoyed cream teas and pink champagne.

At 8pm, they came downstairs for a meal at the hotel's China Tang restaurant with guests including Topshop boss Sir Philip Green.

The billionaire chose a curious jacket decorated with winged creatures for the occasion.

Rolling Stone Ronnie Wood was also there, wearing a policeman's hat with a pig's nose stuck on the front.

Miss Moss's boyfriend, Jamie Hince of pop group the Kills, arrived clutching an enormous present and two packets of cigarettes in one hand and an overnight bag in the other.

Afterwards, the party headed for the Punk Club in Soho.

But before they left, the birthday girl had crimped and curled her hair and painted a gold star over her right eye to enhance the whole glam theme - or perhaps to hide a few tired shadows.

The friend said: "At the Dorchester, all the girls were very busy preening and titillating.

"They were circling round Kate telling her how amazing she looked. But if the truth is to be known, she looked quite knackered."

The group arrived at Punk around 10pm, where veteran Radio 1 DJ Annie Nightingale provided the music, and the girls hit the dancefloor to Kylie Minogue's version of The Locomotion.

At 2.30am it was back to the Dorchester.

Room service was laid on with countless more bottles of Dom Perignon - adding to the eventual £37,000 bill.

The music blared and Miss Moss apparently did a karaoke stint before retiring to a couch for some girlie chat.

Shortly after sunrise she headed back to her new abode, keeping the suites open for a possible return.

The model is understood to have called it a night - or day - soon after.

The friend said: "Kate was quite sick when she went to bed. She's clearly not the party animal she once was."
