I think so. She has a few pictures of Evan on there and she does mention his name a few times. Also she mentions her boyfriend finishes filming in December, which is when American Horror Story finishes filming. I see no reason why she’d make it up, it all fits. Anyways, if you read through it you can make your own opinion on it, but I don’t think she’s making it up.
You mean like his girlfriends blog? Not to the best of my knowledge, but I’m not sure.
