The Westboro Baptist Church plans to picket Elizabeth Taylor's funeral - apparently over her work as an AIDS activist.

In another in a series of increasingly nasty posts, Phelps - daughter of church pastor Fred Phelps - described the late Hollywood icon as a "serial-adulterous f-- hag."

It's unclear how the group plans to target the funeral, since it was expected to be a private family affair.

Westboro Baptist made headlines by protesting at the funeral of a Marine killed in Iraq, waving signs that read "God Hates F---" and "America Is Doomed."

The U.S. Supreme Court ruled earlier this month that the demonstrations were free speech protected by the First Amendment.

Jarrett Barrios, president of the Gay & Lesbian Alliance Against Defamation, quickly denounced the announcement.

"Fred Phelps and his vitriolic anti-gay followers are simply trying to exploit their so-called 'faith' by spreading messages of hate at a time when Americans are grieving the loss of an extraordinary woman, actress and advocate," Barrios told E! News
