Um...so she called some people ugly, got mad and lunged at people taking pictures (I'd probably do this too if I were her, I mean the paparazzi is disgusting, that's why I don't swarm celebrities when I see them), and has been spotted wearing odd clothing and wigs.
I'm thinking maybe she's drunk?
The only part that even seems crazy to me is that she thought there were security cameras in the smoke detectors, if that's really true.
Telling Perez Hilton that he's obnoxious and to kill himself seems perfectly sane to me.
She's saying things that non-famous people say all the time about annoying celebrities. I fail to see any schizophrenia here.
Basically she seems fed up and not an Fe type.
Honestly the worst I would accuse her of is probably being burnt out on being famous, and maybe tweeting while drunk.
I honestly also don't understand how all this adds up to psychosis without the smoke detector story or the hearing voices part. But if Perez Hilton DID make that up, then that's probably why she told him to go kill himself.
