Somehow, I doubt it. It seems like a lot of trouble to go through just for some extra attention. Besides, trying to keep two different lives straight, she probably would've slipped up multiple times.
And is the brother fake too, then?

Pretty much, yes.
And, thanks for not going all rage, like I'm probably going to get in about... a few hours. You're one of those people who are basically like "I doubt that actually happened, because.." and not all "No! That didn't happen, I just know it!". I hate those types of people who just believe whatever they read is a lie. Those who consider it to be a lie, I like.
