I honestly could care less who Zac is dating! haha.
I think Ashley Tisdale is possibly THE most annoying person ever.
And Vanessa is not too much better.
I personally don't think he's dating either of them...
Maybe I'm just no in that loop...but is there any proof or is this all just speculation?
But I don't think either of them would be too happy about THIS;
