Awards season continued at the annual Brit Awards in London last night! Justin Timberlake continued his world takeover, walking the carpet in Tom Ford (of course) before taking to the stage to give his first live performance of his newest single, "Mirror Mirror." (His wife Jessica Biel tweeted her support.) Taylor Swift was on-hand as a nominee for International Female Solo Artist (she lost to Lana Del Rey), and after the show she partied with Carey Mulligan and her husband, lead singer Marcus Mumford of folk band Mumford & Sons, who took home the award for British Group.
