I did read her bio, and you are right. But, her father is how she got into showbiz, and was "introduced" to the world of celebrities, drugs, partying and more, and his professional jealousy was what caused their relationship to go downhill. Her mother was also an actress, who succumbed to a life of drugs and alcohol etc. I am not blaming showbiz itself; it is just how her life was, the child of two actors who happened to be weak, selfish parents, and her own acting career caused problems for her
in giving her access to a sordid world, as well as suffering jealousy from peers, and feeling the need to look for parental love.
