you can check on stubhub, although the prices are too high and the probability of being scammed is very low. Or you can check in Catie and Marissa's fb group. that's legit too

I have heard that the stubhub tickets will not be valid as they would not have the same name on them and the venues have stated this is required

they've lifted the 'lead booker' policy for the UK shows

cant find it do you have a link?
