SEE PICS! The starry St Trinians 2 premiere

Here come the girls... Leicester Square was awash with fashionable females for the premiere of St Trinians 2: The Legend of Fritton's Gold

Here come the girls! Leicester Square was overrun with fearless females last night, when the cast of St Trinians 2 hit town for the film's UK premiere.

Lock up your sons, because the St Trinians girls were out in force...

The time-honoured red carpet was stripped up and replaced with a punky pink version, ready for the stiletto-heeled army of starlets to charge down it.

And the naughty schoolgirls were looking decidely more glam than their on-screen counterparts...

Stealing the show was Sarah Harding, who made her silver screen debut in the 2007 fore-runner of the family-friendly flick. The songstress went for high-octane glamour in this sparkling fishtail Georges Chakra couture gown, which had sheer cut-away panels. 

We're sure Ms Harding must have been nervous on the night - because not only does she feature as one of the girls in the film, she also recorded the theme tune.

Keeping Sarah company were fellow bandmates Nicola Roberts and Kimberley Walsh.

Nicola simply shone in her white structured frock, which was covered in ruffles and crystal embellishments, while Kimberley cut a super-svelte figure in her strapless LBD.

There was a definite monochrome theme apparent on the pink carpet, and Nicole and Kimberley weren't the only yin-and-yang couple to attend.

The impossibly pretty pairing of Talulah Riley and Tamsin Egerton stepped out in their contrasting Alberta Ferretti gowns, with Talulah opting for a glam black column dress, and Tamsin in a draping white Grecian creation.

Adding some brighter-than-bright bursts of colour to the evening's proceedings were a couple of fiesty females, Paloma Faith and Shingai Shoniwa - who also seemed to be competing in the tallest hair stakes.

Paloma was her typical off-the-wall self in a bold orange jumpsuit, paired with vertiginous platforms and a red embellished trophy jacket.

Shinghai arrived flanked by her bandmates from The Noisettes, and co-ordinated with the carpet in her vivid pink Jean Pierre Braganza minidress - previously seen on Cheryl Cole in the X Factor.

The night didn't end after the film screening, with the stars all moving on to a lavish afterparty.

Sarah Harding switched from her full-length frock and into something slightly more party-appropriate, in the form of this pleated pink Atelier Versace dress.

But our style flop of the night came courtesy of Gemma Arterton. The former Bond girl turns Head Girl in the comedy romp, and was sporting a black Alexander Wang maxi for the evening. While perfectly nice, it hardly had the wow factor on Gemma - but it was her bed-head hair and messy make-up that we found particularly surprising...
