How common is it for a woman to actually brag about living off a man's money?

I was chatting with a woman last week at a social gathering and was asking what she did for work. She responded "I don't do anything to receive money." Her husband makes a good income and she seemed quite happy to brag about living off his money so that she could operate her "business" (hobby) which doesn't make any money. BQ: How often to men brag about living off a woman's money?
