actually, Rob did speak to the Sun, they just twisted his words. The Sun reporter asked: is this a public appearence together? and he replied: yes we are together. The Sun made an assumption. This is not to say they arent together- they may be, but he hasn'e officially "revealed" they are a couple (unless that was his VERY subtle way of telling us ;) )
I'm not sure either, i just wished the two of them would tell us, a clear yes 또는 no. The stories and the gossip doesn't really help, i think the press should leave them alone, until they are ready to finally tell us!
