No matter what Cynthia "Plaster Caster" Albritton, Pamela Des Barres or anyone else says - the management for Jimi Hendrix's estate says a sex tape doesn't exist.

Vivid Entertainment said last week that they have obtained a sex tape with Hendrix and two unidentified women.

The video was said to have been authenticized by the likes of Cynthia "Plaster Caster" Albritton who is famous for making penis plaster imprints of celebrity's penises and Jimi's former lover Pamela Des Barres. Impressive, eh?

No matter what, the estate says it isn't true.

"We strongly dispute the claimed authenticity and affirmatively state that Experience Hendrix is neither involved in nor have we authorized the distribution of this film," a statement said.

"Further, we deplore this obvious exploitation of Jimi Hendrix," it added. "We are highly offended by the disgraceful portrayal."

The porn giants at Vivid say they still plan to release the video, "Jimi Hendrix: The Sex Tape."
