Bookout, who shares her 8-year-old son Bentley with Edwards, said she believes he is willing to enter rehab, but "it's everyone around him who's afraid .. afraid of what it will look like, more than his health."

She says she's the only one "who sees everything and cares."

The mother of three added that she fears that "today's gonna be the day that Ryan does something that he can't come back from."
