The rapper and wife Kim Kardashian West visited a London recording studio following yesterday's ceremony, and weren't pictured leaving the studio until 4am.
Kanye had performed track 'All Day' at the Brit Awards and was clearly still feeling inspired as he spent a few hours in the studio with his reality star wife.
He hit the stage at London's O2 Arena with a huge mob of dancers accompanied by flame throwers for an energetic performance that was so full of swear words ITV had to keep muting the sound.
Poor Kim must have been a bit knackered!
She only arrived in London from LA yesterday morning, went to her hotel, got changed and then joined Kanye at the BRITs where she presented an award to Sam Smith and introduced her husband's performance.
Then, it was off to Hakkasan for a quick dinner before the studio.
Why is Kim Kardashian famous? Find out below!
Kim, 34, didn't change out of her sexy Julien Macdonald jumpsuit or spiky heels after the awards – we hope her feet aren't hurting too much today after hours standing in those!
She presented friend Sam Smith with the 'Global Success Award 2015', honouring his huge success outside the UK, including a slew of Grammy Awards earlier this month. Kim also got a selfie with Ant & Dec on stage.
The star will now fly back to LA to collect daughter North, one, before heading back to the airport to fly to France for Paris Fashion Week.
