As you no doubt know, One Direction's massive Take Me Home World Tour kicked off in London this weekend and whether you've got tickets or will be enjoying the experience through the medium of YouTube videos, we've got all the pics of what went down.

That includes Niall Horan exposing his nipples and lots of dancing.

It's good to see that Niall got straight back up on that horse and whipped out the electric guitar to show everyone how tough and manly he is.

At least, tougher and manlier than Louis and Liam, who appear to be playing skipping games in the background while Harry plays a round of hopscotch.

YOU THE MAN HAZLAN. But you do know that hand is only covering up one of four nipples there, right?

Casually arriving on a flying platform. We like how Harry, Zayn and Louis are in suits and you get to Liam and Niall and they're like, 'Nah, I'd rather wear something that shows off my crotch bulge a bit more.'

We think that every day.

Oh HELLO Niall Horan's nipple exposing vest, let's be friends.

Isn't it about time somebody named Goldilocks' right nip that's always on show? We're thinking Nigel. The left one can be Nancy.

Moody acoustic strum-times with Liam in his oh-so-sensible fatherly lumberjack shirts.

It's HOT.

1D take their lives in their hands to perch on a beam. Well, apart from Liam, who is far too sensible and Louis, who probably wasn't allowed in case he had a sass-explosion and fell off, dragging Zayn with him.

It wouldn't be the first time.

When all else fails: OUTFIT CHANGE.

Phwoarr, this is more fitness than our ovaries can handle.
