She was named Woman Of Tomorrow at last night's Glamour Awards - and fans of Jessie J will be wondering just what the star is going to look like in the next 24 hours after she underwent an amazing transformation for the bash.

Jessie - real name Jessica Cornish - had ditched the severe black bob of a few days ago for hair extensions in a stunning soft and wavy style that almost brought to mind 1940s pin-ups.

The 23-year-old star also showed how pretty she could be by smiling naturally on the red carpet at the Berkley Square event, rather than pulling her trademark pouting pose.

Sassy to sexy: Jessie J looked stunning on the red carpet of the Glamour Woman Of The Year Awards in London last night - and totally different to when she arrived at Britain's Got Talent last week

Her punky make-up had been replaced with a a more polished yet barefaced look, with just a pair of false eyelashes as embellishment rather than her more usual experimental studded or painted lips.

And the brunette beauty also struck a more typical catwalk pose with her hand perched on her hip, rather than throwing her usual peace sign.

The Do It Like A Dude singer had swapped her more normal 'underwear as outerwear'/borderline fetish schtick and basques for old school style.

She was wearing a figure-hugging strapless black sequin Dolce And Gabanna dress from their new season's collection and looked sensational.

The Price Tag signer joined guests including Kim Kardashian, Kristen Stewart, Fearne Cotton, Kirsty Gallacher, Louise Redknapp, The Saturdays, JLS, X Factor's Louis Walsh and Tulisa Contostavlos and Dizzee Rascal.

After the awards ceremony, a host of stars stayed to a shake a tail feather to DJs on the dancefloor and down Disaronno and Cointreau cocktails.

David Gandy and Mollie King were seen kissing all night long over Disaronno cocktails, whereas Katherine Jenkins and Gethin Jones were spotted whispering sweet nothings in the corner over a Cointreau Rose.

As well as the sumptuous drinks, guests were also treated to incredible goodie bags as they left the party.

Looking sweet: Sugababes Amelle Berrabah, Jade Ewen and Heidi Range were out on the town for the first time in a while last night too - maybe it was the lure of the goodie bags...

Stars were staggering home with the weight of each carrier containing a bumper bonanza of freebies.

Tha haul included Dawn French's acclaimed book A Tiny Bit Marvellous, Godiva chocolates, a tube of Dove Damage Therapy Intensive Repair conditioner, a bottle of Wellaflex Heat Creations blow dry spray, a pot of Nicola Roberts's Dainty Doll blusher and St Tropez bronzing mousse.

There was also a can of celebrity favourite Elnette hairspray, Elegant Touch metallic false nails, CCS foot cream, Joop! Homme Sexy In Pink eau de toilette, Benefit blusher, Nails Inc limited edition nail varnish, Eyelure false eyelashes and some samples of cult hair product brand Moroccanoil.

Take your mama out: Fearne Cotton, who won the Radio Personality award, had taken her mother out as her guest to the after party

On white on the night: Naomie Harris won the Theatre Actress of the Year award at the bash

Good time girls: Una Healy, (L) and Vanessa White (R) of the Saturdays also went to the May Fair hotel after the awards ceremony, where their group won Band Of The Year

Rod Stewart's wife Penny Lancaster appeared to have got stuck into the free bar at any rate, and danced up a storm, having let her husband go home early to look after their four-month-old baby Aiden and Alastair, five.

Other guests however took the party elsewhere, with the likes of Tulisa, Eliza Doolittle, The Saturdays and Alexandra Burke choosing to head to the May Fair, and Rosie Huntington-Whitely heading to Mahiki.

Jessie meanwhile, who released debut album Who You Are in February and has already seen it go platinum in the UK, went back to the Sanderson Hotel to celebrate.
