I remember finding this set on a website which you have to pay to see the full size, unwatermarked, versions of their images. I have another few small versions from this set somewhere. They're mostly shots of Justin on and around a property - so you're probably right with your guess.
EDIT: Oh, I just found my versions: they were listed as being from the same collection but these have a black background to them. I just put them in the photoshoot section.
