So let's get this straight: they were rumoured to be dating, then he denied it but now it seems he was bluffing and they are an item really.
Does anyone else's head hurt at this point?

And now it's believed that things are going so well that the smitten pair are planning to spend Christmas together in sunny LA.
Well, it's alright from some, eh?
Liam and Leona are obviously both super busy most of the time being super pop star types however have managed to pencil in a few days over Christmas.
And they are both reported to be super excited to get some much needed alone time.
So it would seem it's not just Harry Styles who loves a cougar!
A source told The Sun: "Leona and Liam only starting seeing each other recently."
"But because of work, they won't be together for a while now."
"They thought this was a nice thing to look forward to."
However, even as we write this we still can't quite believe Liam and Leona are an item, and just can't get over the fact she previously said *this* when asked if she would ever date a member of One D:
"Liam's sweet, but they're, like, two."
We wonder what it was that changed her mind?
