Lily Allen and her trendy-ite crew were on the mother of all benders last night. Their day started at 10.45am at the Luella fashion show in Claridges and hardcore Lily was still going strong at 2.45am this morning, after a whopping 16 hours.

Judging by the photo, the singer will no-doubt be nursing a sore head this morning.

Lily, who's had a tough couple of weeks, went to the Vivienne Westwood show with Kimberly Stewart, Kelly Osbourne, Alexa Chung, Jaime Winstone and Peaches and Pixie Geldof last night. The usual suspects.

The gal pals then hit up the after-party in Dolce club and managed to fit in the Hadley Freeman book launch in Mulberry on Bond Street on the way.

But Lily wasn't content to leave the night there and she headed off to Punk in Soho - finally running out of steam and heading for home at 2.45am this morning.

Lily and her gal pals hit two fashion shows including Vivienne Westwood's, an afterparty at Dolce nightclub and a book launch before ending their night at Punk nightclub

The 22-year-old, who is nursing a double heartbreak after losing her baby and splitting with Chemical Brothers Ed Simons, appeared at the show in a plunging red dress, set off with dark smokey eye makeup.

Flashing a smile for photographers, Allen seemed to have also put behind her the stinging criticism of her new BBC3 TV show, which reportedly saw members of her audience walking out in boredom.

Meanwhile Alexa Chung said she wasn't able to do any smooching on Valentine's Day adding: "I'm not even going to be able to have that much fun tonight as I've got to be up at 6.30am to present T4."

No doubt that Alexa will make it up to her Arctic Monkey boyfriend Alex Turner over the weekend.

Brit actress Jaime Winstone, daughter of Ray Winstone, took to the catwalk, as did Daisy Lowe, and the girls were cheered on by Rod Stewart's daughter Kimberley Stewart and Kelly Osbourne, who wore a plunging red dress almost identical to Allen's.

As well as the usual lashings of Westwood glamour, last night's show also featured a specially designed pair of "Guantanamo Orange" knickers designed by the charity Reprieve, in conjunction with Agent Provocateur, the lingerie firm founded by Westwood's son, Joe Corre.
