Sources close to Adrienne tell TMZ she has had multiple talks with the show's honchos over the past few months ... discussing her desire to leave the show.
We're told Adrienne believes the intrusiveness of the show has "ruined" her family and personal life.
Our sources also made it clear ... Adrienne's departure has nothing to do with finances (she's worth millions), catfights with other cast members, or her recent divorce from Paul Nassif -- with whom she fought constantly on the show.
Fact is ... Adrienne may be beating producers to the punch. We're told she and Taylor Armstrong are on the chopping block and their replacements are already being cased. As we first reported, former "Extra" host Dayna Devon is currently a front-runner, along with Rod Stewart's wife, Penny Lancaster.
