And he's hungover to bits while doing so too.
Well not really, but he does admit to being out until 6am and if we're to go along with the idea that Derulo is accompanying Corden on his morning commute, that probably means he hasn't gotten very much sleep at all, if any. His miracle cure? Coffee, apparently, and he's 'Gucci' with just one cup (which is an awful phrase that we cannot as a species allow to become a thing).
It all starts with a singalong and goes to Derulo giving a dance lesson in a petrol station forecourt before the pair hijack a Starline Tours van with a load of tourists. Good, but still no Mariah.
