One of the fake online personas Shannon claims Ryann has created is that of a high school cheerleader.

“Ryann wants the life of being the head cheerleader who’s going to get the popular boy. Ryann sprained her wrist once from a bicycle accident, but told the boys on social media it was due to being on top of a [cheerleading] pyramid and the girls dropped her,” Shannon says. “It’s her fantasy world.”

Ryann denies her mother’s claims, however, Shannon claims her teenage daughter has also gone as far as to lie about being pregnant in order to get a boy to commit to a relationship.
