Where's Leah Remini? Holly Robinson?

It's been weeks since I last saw these two favorite hosts of mine on The Talk. Where are they? I am not suggesting that the new replacements aren't as good and as funny, in fact they are equally brilliant and humorous, but I just feel like the two women's exit was just too abrupt. They weren't even given the opportunity to say goodbye to their avid viewers. I read somewhere that they weren't invited back to the table on this season's airing. I wonder why. Someone should take this up at the table in one of their episodes. I believe the viewers need some explanation.
