Taylor Swift joined BRIT Awards show host, James Corden, behind the decks at the Universal Music official BRITs after-party last night (February 20).

Donning a pair of headphones, Swift who performed at the show, helped Corden pick tracks to play at the Soho House POP UP in East London. 

Carey Muligan and her husband, Marcus Mumford from Mumford and Sons, celebrated his success for winning the Best British Group award.

Both Rizzle Kicks' Jordan Stephens and Frank Ocean took turns to chat and dance with Swift.

Elsewhere in London, Swift's ex, Harry Styles went on a party crawl with pal, Nick Grimshaw, around all the after-parties, resulting in both turning up without a wink of sleep to Grimshaw's BBC Radio 1 morning show.

Lily Allen tweeted whilst the bleary-eyed boys were co-hosting: "@grimmers you sound hammered still". Watch the performances of Taylor Swift and One Direction at the BRITs 2013 below:
