Even with the assistance of a network and several producers (all of whom are probably in on the scam) Tori and Dean weren't able to cover all their bases and as Jezebel recently pointed out, there are a few things about True Tori that just don't make sense any it's very possible that Spelling and McDermott are lying to the cameras:
For starters, Spelling definitely lied about the time McDermott spent in rehab.
She claimed on the show that he was away for several months beginning in mid-December and she stated that she spent Christmas alone with the kids.
The problem is, McDermott was active on social media during those months and posted photos of himself enjoying Christmas with Tori and the kids. Whoops.
She's never been photographed, she hasn't given an interview since her name was first revealed in December and a thorough search of all social networking sites turns up only one Canadian named Emily Goodhand and the woman swears she's never met McDermott. Whoops again.
There's more damning evidence such as Spelling's alleged deal with Us Weekly (the tabloid has been publishing "affair exclusives" for months) and the fact that Spelling wrote about making up storylines for her previous reality show in her latest book, Spelling It Like It Is.
So yeah, True Tori is almost certainly entirely scripted, but that's the case with most reality shows, so you may as well enjoy it for what it is: a primetime soap opera with really bad actors.
