She arrived late at the studio, Fern and Phil just about had time to say hello before opening the show. So they didn’t get a chance to speak to her beforehand and neither did anyone else. What amazes me is that the interview was allowed to continue, but then it is live. I am sure that everyone has drawn their own conclusions as to what she had taken/been taking, but as Mary J said, that kind of medication does have adverse side-effects. Easy to judge because of her past history, her husband should have called the whole thing off, but he didn’t because she was there to promote her MTV show.
If she doesn’t slow down though I can see her heading for a meltdown a lá Britney style.
