We're all over those overalls

So yesterday we headed down to a go-karting track to hang out with One Direction while they were promoting Mario Kart 7 for the 3DS.

The boys had all donned red overalls (like Mario, geddit?) and were busy playing the game themselves in between whizzing around the go-karting track and having the best time of their lives chatting to us.

We've got loads more snaps of the boys from the day, including a very gratuitous bum shot from behind. Thanks Nintendo.
