Last night we almost froze our toes off walking through London - and we were wearing UGGs! So we're very impressed (and slightly sympathetic) for all the celeb ladies who turned up for the premiere of Valentine's Day in tiny dresses. Jessica Alba, Demi Moore, The Saturdays, Emma Roberts, Emily Atack, Nicola T and Dionne Bromfield all went without coats in the FREEZING conditions, and Tamara Ecclestone (in black and white with red shoes) could barely disguise the frozen grimace on her face. At least Ashton Kutcher and Topher Grace were alble to cover up a bit more, but even they looked chilly in their suits. We don't know how these ladies do it. We've added a gallery below for you to look through and pick out your favourite outfits. Personally we like Hofit Golan's pink and purple effort...coughNOTcough
