When asked about a potential premiere date for season 13 of RHOBH at last week's People's Choice Awards, costar Kyle Richards said, "I think 'pause' is the word of the moment; it sounds more dramatic than it actually is. I think we just kind of want to shift our schedule."

Richards explained of the typical timeline: "We used to start in April, it's kind of inched its way over the years, but we are starting later this time. People think there must be some drama, 'they are starting late,' it's not that serious."
