Taylor Swift and Jessie J have particularly caught our eye - both are wearing stunning black numbers. The 'Trouble' singer is still showing off her legs with mesh panelling across two thigh hight slits in her dress, whilst Jessie J has gone for the opposite look, covering her legs and showing off her chest in a particularly low cut number - sexy! Check out the ladies outfits here.

14:44 - We've been snooping around backstage at the O2 ahead of tonight's awards show to give you all of the inside goss. So far we have spotted manicurists, fake tan booths and masseuses - the BRITs have got everything covered.
But it's not all pampering and glamour, we've also taken some snaps of the hard work being put in to make the stage look fit for pop princes and princess, and of course the dressing rooms where the acts performing tonight, including One Direction and Taylor Swift, will be getting ready. Maybe we will hang around here for a bit longer...
As the stars arrive at the O2 Arena in London, Capital has crept backstage with our camera to bring you all the action.
14:01 – Hello, and welcome to backstage at the BRIT Awards. This is your number one place to find out what's happening in the build-up to tonight's ceremony at the O2 Arena.
