Speaking on the edition of her talk show Bethenny due to air today, Frankel explained that she does not watch the series "religiously" but will "sometimes catch up".
"It's not anything against them," People quotes Frankel as saying. "I've been busy planning the talk show and kind of doing my own thing. It was a long time ago."
Frankel explained that she is "grateful" to the show because of the opportunities it has brought her, but added: "It's a totally different show than when I started. It was just about women who had children and were married and it was kind of more fun and playful.
"Then it got crazy. Then it got really crazy and it was a different show."
Frankel recently used an appearance on Bethenny to deny rumours that she is going to get divorced.
