This show is gold for one network but the two co-stars hate each other
. A lot. As in, if they have to do something together, they will, but otherwise they don't speak. Both are very likable individually, but one is the perceived star and acts accordingly and the other does not like her for it ans has called her out on it. The actress who is the less perceived star is probably going to be replaced because they have deemed her easy to find anywhere while the other co-star would be impossible to replace with the same kind of talent.
