According to Extra TV on Friday, Frankel said, "People have an opinion that I'm thin, people have an opinion that other people weigh more or curvy, everybody's got an opinion. Dress for success is my chosen charity, this shaming of skinny people is just not something I'm willing to get into. Woe is me, I'm thin and people make fun of me, there are bigger problems."

As far as her comments about being "the richest homeless person in New York," Frankel said, "You can't even say anything without everyone attacking you. Now I'm offending the homeless. I donate so much money and help the homeless, it's called humor. It's irony, it's just everyone's so sensitive."

The Real Housewives of New York airs every Tuesday on Bravo.
