Pregnant star Kim Kardashian attended wearing skin tight leather trews and an embroidered top. Those feathers are an interesting way to cover a little baby bump.
Topshop fan Emma looked cute in her multi-print frock and stacked heels. What's with the opaque tights? It can't be that cold in LaLa land!
How gorge did Revenge star and Brit babe Ashley look in her curved hem frock? We love those simple strappies, too. Ash wasn't the only Topshop lover to sport this Toppers frock last night...
She's a long way from Essex, babes! TOWIE's Lauren also wore this printed mini but gave hers an Essex spin with giant tottering platforms.
Another Revenge lady, another lovely look. We love this sweet co-ord with OTM white heels.
Helping to fly the Brit flag, Russell Brand took time out from his busy yoga life to pop along.
She was the star of Topshop's first ever film, showing off surprisingly good vocal chords, so of course Bosworth was going to be at the big launch! The newly-brunette actress looked fab in her cut out printed dress.
Libery brought a big dose of cool to proceedings in her vibrant green origami dress and strappy patent heels. Love her nonchalent simple 'do, too.
A space-age J-Lo took her boyf out for a night of pre-Valentines Day fun. Again, what's with the thick tights!?
Sir Phillip's daughter Chloe went for rock chick in a tummy baring crop top and leather skirt.
One woman not feeling the chill was Kelly O who showed off her bra in a daring ensemble. We're not overly keen on the outfit but that bright pink lippy is a YES.
Trendsetter Solange rocked a cool check teamed with stacked heels and an oversized boyfriend blazer.
Wowzers! Katherine and her impressive cleavage rocked up to the bash wearing one of Topshop's printed frocks.
Paris didn't really make our jaws drop with her boring LBD.
One of the hottest trends at the moment, bold stripes, and didn't Julianne wear them well?
Another monochrome madam. Nic opted for a floaty dress with over-the-knee boots.
Where have you been hiding yourself, Jess? When you're looking this good it's just rude not to show it off.
Seriously, girls. Tights. In LA. What's happening?
Luckily for Demi, her power pink pout saves her from being a dullard in black.
Is that a Valentines Day-inspired outfit Chris? Perhaps sending a special someone a message *cough* Rihanna *cough*.
