Yeah she seemed really bitter on Twitter about it too, said she was mad that she did the job for 20+ years and never got any awards or higher pay. She said playing the "mommy" role made her sick and that she hope God could forgive her for depicting incest. She also said she couldn't compete with the gangbangs, squirting, and other things that have taken over in porn. Seems to have found God also.
Sucks because she was always one of my favorite performers. Always so sexy at any age. I wish her the best.
