Tina Brown, Whitney Houston's sister in law, has come to the conclusion that Whitney has a brain tumor. What ELSE could explain her erratic behavior over the last several years? There is NO OTHER explanation that comes to mind. Is there????

Brown says, "The talk in my family is she does (have a tumour). (A family member) said the other day, 'It's getting worse. Let's take her to the hospital.' And (another family member) said no because of the media.
"She's (Houston) going into her states and everything. All the symptoms are there. "They called from California stating that she had a tumour. Why are they keeping this a secret, I don't know."
