London's party posse were out in full force last night at the première of the new Batman film The Dark Knight. Four of Brit's brat-pack took to the red carpet, choosing mostly black ensembles, to blend in with the film's cast who continue to pay tribute to their late friend Heath Ledger.

Want to know what they wore? We'll tell you after the jump...

Kelly Osbourne chose a subdued, slicked back look for her appearance last night. However, her sheer black lace L'Wren Scott dress didn't seem to go down to well in the press, with the Daily Mail calling it 'garish' and 'anything but demure' due to its see-through fabric. Yikes!

Meanwhile, Daisy Lowe and Alexa Chung opted for different looks with Daisy vamping it up Gothic Lolita style in a plunging black dress with ruffled cape by Kristian Aadnevik, and shiny heeled boots. T4's Alexa dabbled in a '90s secretary style, wearing a cropped black skirt suit combo, loose white top and heels all by Chanel. Although it would have been nice to see her dress up a bit more for the occassion, I actually don't mind this conservative style on her.

Finally, Peaches Geldof made a surprise appearance, after reports that she suffered a drug overdose on Sunday (blimey!). The 19-year-old chose, what else, but PPQ. The clown-like prom dress, suited the 19-year-old's youthful style and added a quirky touch to the evening.

So, who do you think looked the best out of the bunch? I leave it up to you decide - tell us below.
