I know it doesn't have anything to do with anyone but I was just browsing the net and stumbled across the pictures of them on there recent holiday to the Caribbean (I think) and I saw the 2 pictures that made me wonder.But here is the question. . .Do you think Zac and Vanessa are sleeping together you know like intimate with one another?!
