Osbourne -- who appears on the TV show "Fashion Police" with Joan Rivers -- took to Twitter to voice her concerns. "Any 'friend' of Amy's talking 2 the press/tv are not her actual friends. Her real friends have more dignity then to get $ 2 talk about her!"
She also said she was fed up with all the negative responses appearing on her page and may not want to continue using the social networking site: "Don't think I want a Twitter page anymore the fact that ppl get joy from being mean 2 me makes me sick what's the point? there is too much evil."
One of the targets of her criticism was believed to be Aisleyne Horgan-Wallace -- a former "Big Brother" star in the UK -- who did not attend Winehouse's funeral, but went on a British TV program on Wednesday to talk about the late singer. Horgan-Wallace was seen in tears on the show as she spoke about Winehouse and denied a report that she was out with the singer just days before her death.
Osbourne also used her Twitter account to speak out against her former fiancé Luke Worrall, whom she said posted negative comments about her while she was at the funeral. "@luke_worrall it was fine when my Kellyphant ass was paying 4everything wasn't it? I just didn't think u could get much lower but u did #wow," she tweeted. "@luke_worrall you've made it very clear u only dated me 4 my life style but s*** tweets about me the day I'm @ a funeral u have hit a new low," she added.
