What twitter account is this? It is rumoured that they are dating, but there's nothing official. I think it's a fake twitter account. Katie recently said that she doesn't have it, and she's not going to get it.
No, the cast, as you can imagine, are just all really good friends since they spend over 8 monthes together whilst filming, so like any friends they'll go around together and take pics together, but that doesn't mean they're dating. Also, katie does have a real twitter account, but she hasn't used it since the 14 feb ( It's (Real KTMcGrath) xx
