Look what I found:
I've come across online just the other day and it really sucks. I was really looking forwards for the new series with Holly Marie Combs. She hasn’t been doing any new movies or other projects scents Charmed besides Panic Button. Tekken and Triangle she is not in any more either.
an article online that reports of Lifetime network picking up a show called 'Drop Dead Diva'. At the end of the article there's the following tidbit: "'Diva' was one of several pilots in contention at Lifetime, along with 'Mrs. Novak' and 'Mistresses.' The other two are not going forward."
HollywoodReporter.com is a rather reliable source so I'm afraid this means that unless some other station picks it up, Holly's new show Mistresses has been cancelled!
I'm really bummed right now. I guess there's always a chance that the pilot leaks and we still get a glimpse of Holly Marie Combs, right? And hopefully Holly won't feel too disappointed and she'll be back with other projects soon!
