Scheana Shay's new book, My Good Side, is full of SURprising details for Vanderpump Rules fans - including the reveal that she wasn't a series regular for seasons 8 and 10. "They said, 'The audience is never going to know. You're still going to be in every episode, you're still going to be in opening credits. You're still a main character, you're not anyone's 'friend' of,'" Shay, 40, tells Us Weekly during an interview for her cover story, noting that the same thing happened to Kristen Doute for season 7 and James Kennedy for season 8.
