But last night the Essex girl toughened up her look as she took to the DJ decks in London.

Lauren Pope may have worn a pretty white pleated skirt but she paired it with a fierce black cropped tea with a skull on it as she went for a rockier style last night.

And she completed her tough-girl look with a pair of black bold heels.

She posted: "Just bein dead subtle behind the DJ booth using my CD's as a fan cos its so hot in hurrrrrrr!!"

Busty Chloe went for more of her usual style - in a tight white bodycon mini dress and nude stacked heels.

And she posted a gorgeous picture of the two TOWIE girls partying together.

She tweeted: "Casually doin bits last night @LaurenPope" alongside a pic of them sharing a girly moment as they posed for the camera.

Meanwhile Big Brother star Nikki Grahame also attended the party - despite her broken arm.

Nikki looked cooler than we've ever seen her in a pair of beige pyjama trousers, white tee and some geeky specs.
