The Troublemakers

Louis and Katie Tomlinson, where do I begin with them?
They've been married for four years now.
Their two year old troublemaker-I mean son-keeps their hands full.
But what happens when they find out that there's another baby on the way?
How will Jordan take it?
Like most two year old's obviously.
And what about One Direction's upcoming European tour that's supposed to begin right before the baby's due?
