The way I see it - Dan and Emma both knew those pictures were being taken. They know how damaging it would be to be branded liars - as that's what they would be if Dan said this when he is in fact seeing her. I dont think he's the dishonest type and besides if they lied that'd be awful press not to mention how many littler fans that could upset. And we all know how WB like to cater for the kiddies!
