They're well on their way to becoming bonafide pop stars following their performance on The X Factor on Saturday night.

And Tulisa's girl group Little Mix certainly looked the part as they arrived at the InStyle magazine's 10th anniversary party in London tonight.

Despite their baby-faced looks, the foursome certainly looked grown-up in their sexy ensembles as they arrived at the Sanctum Soho Hotel.

Celebrity lifestyle: X Factor finalists Little Mix (L-R) Jesy Nelson, Leigh-Anne Pinnock, Perrie Edwards and Jade Thirlwall arrive at the Film InStyle 10th anniversary party at the Sanctum Soho Hotel

Essex barmaid Jesy Nelson, 20, showed off her curve in a pair of tight leggings and gold top, while High Wycombe waitress Leigh-Anne Pinnock, 19, went for a Twenties-inspired outfit in a fringed bandeau dress.

South Shields duo Perrie Edwards and Jade Thirlwall, both 18, wore an all-black ensemble and a red dress respectively, with the latter opting for the recent resurgence in wearing stockings.

Following their rendition of En Vogue's on last weekend's 'Movie Week' themed show, Little Mix are now 15/8 odds to win the series.

No rivalry here: Misha B went for a less flamboyant hairstyle than usual, while Amelia Lily wore a pink Topshop dress

They've certainly gone from strength to strength from originally tipped to be an early exit due to the historical lack of success for girl groups on previous X Factors.

And while they're yet to graduate from reality stars to pop stars, one celebrity was already star-struck by the girl band.

Fellow guest Pixie Geldof admitted she was too shy to approach the band.

She tweeted: 'Totally devd! Was too shy to talk to @LittleMixOffic at InStyle party and now they're gone!!!!! #eternalsadface.'

Also at the event were their fellow X Factor finalists Amelia Lily and Misha Bryan.

Manchester-native Misha, 19, was nearly unrecognisable without her signature flamboyant hairstyle as she turned up with a poker-straight bob and fringe.

Hollywood glamour: Actress Gillian Anderson flashed a bit of leg in a white 1970 vintage Christian Dior gown

Meanwhile, Middlesborough student Lily, 17, matched her new long pink hair extensions with a baby pink sequinned Topshop dress.

The film-themed event to mark the 10th anniversary of the UK edition of fashion glossy InStyle showcased specially-commissioned films by designers House of Holland, Diane Von Furstenberg, Christian Louboutin, Paul Smith, Mulberry, Zac Posen and Roberto Cavalli.

Entertainment was provided by T4 presenter Jameela Jamil in the DJ booth, who wore a trademark mini skirt to show off her long legs.

Keeping it low-key: Pixie Geldof, who was too shy to talk to Little Mix, covered up in a double-breast jacket, while Ronnie Wood's ex-girlfriend, Brazilian polo player Ana Araujo wore a tailored jacket and trousers

Floor-length and fabulous: Pop star Diana Vickers looked grown-up in a long black gown, while former X Factor stylist Grace Woodward gave hers a vintage twist

Looking super glam at the bash was actress Gillian Anderson, who looked stunning in a white 1970 vintage Christian Dior gown.
On the other end of the spectrum, black was predictably a dominant colour of choice for many star's outfits.
Diana Vickers wore a long black gown, while former X Factor stylist Grace Woodward gave her quirky floor-length number a vintage twist with her accessories.
