Sometimes the question of "which revolves around which" is difficult to answer, because the two objects actually "orbit" around an imaginary point called the barycenter:



If two bodies are similar in mass, as in this animation, then this barycenter around which they revolve will be outside both bodies, so one can't say that one goes around the other. (But in the Sun-Earth orbital system, the barycenter is deep inside the Sun, although it's not exactly at the Sun's center -- so for all practical purposes, "the Earth goes around the Sun.")

But I doubt that "Mrs. Zhirkova" was thinking about such subtleties!

Меня смутила не Жиркова, а сам факт, что она победила в конкурсе на звание Миссис Россия. Что там за конкурентки были и что за судьи?

И какой вообще смысл в этих конкурсах?

That's true but only for those who fly in a spaceship far away from the two revolving bodies, in other words these two bodies are revolving as a dancing pair in the interstellar "frame of reference". If you stick yourself to one of the revolving body then for your "frame of reference" another body will be revolving around yours keeping you and your "frame of reference" stable. What "frame of reference" was in the consideration is not clear from the talk. Well, you can tell that Mrs. Zhirkova was not thinking about such subtleties. Well, I agree, as well as I agree that the interviewer was not thinking about the same subtleties either. So the appropriate question got the appropriate answer.
