I was one of her friends on FB, too, and I became more and more disgusted with what I saw there. Now she's shut down her FB pages and she's over on Twitter. What I particularly dislike is the way she attacks Kenny Ortega, AEG, Michael's lawyers, etc. She acts as though they wanted Michael to die and were all in some kind of plot to kill him. That's so ridiculous. They were going to make a fortune on those concerts.
On Twitter she keeps moaning about how heart-broken she is, she can't get over it, etc., etc., as though it's all about her. She's upset about the estate lawyers signing the contract with Sony, like they were in a plot with Sony, too. Michael's problems with Sony mostly had to do with Tommy Mottola. Sony is the only record company big enough to pull this off. After Motown, Michael was always with Epic/Sony. Karen thinks the family is being shut out and should be included in decision-making, but Michael left them out of his will and the court has said they have no standing. I'm happy the estate lawyers are taking such good care of Michael's body of work and his children will be able to benefit from it.
Before his death, Karen was enthusiastic about the concerts. One more thing - she knew him for many many years and must have been aware of his abuse of prescription drugs. Why didn't she do anything about it? She blames everyone else.
I think she's nuts, personally, and enjoys all the attention she's getting from the fan community.
