"Real Housewives of New York City" breakout star Bethenny Frankel has had many moments in the spotlight.

Between her magazine covers, booming business, and successful book, the star is everywhere. But she's never been exposed quite like this before.

This time, it's Frankel's nude body in the spotlight -- specifically in a giant ad in NYC's Times Square -- proclaiming those famous words, "I'd Rather Go Naked" (than wear fur) in support of the People for the Ethical Treatment of Animals.

And, might we say, all those Skinnygirl margaritas have worked out. The woman is in great shape!

According to the PETA, Frankel said, "I used to wear fur. I went to a cocktail party...and a PETA protestor was holding up a skinned animal. I looked at it, and it made me sick." The star changed her mind about mink, and says "Since then I've really been against fur."

Unfortunately for Frankel, after the ad was unveiled at noon on December 15th in NYC's Times Square, some fellow housewives had some less-than-nice reactions.

New Jersey Housewife Teresa Giudice tweeted her distaste for the photo, claiming, "I just threw up a little in my mouth," and after Bethenny was quoted in an article saying she was pleased with what appeared to have been minimal airbrushing, Giudice tweeted "I'm not buying the airbrushing thing in any case."

Instead of getting back at Giudice by, say, flipping over a table, Bethenny fired back by posting the untouched photo for all to see, telling US Weekly, "If people are talking and saying [the photo] was airbrushed...then, you know what? Here's the picture. Have it your way."

Take a look at both photos below -- we think Bethenny looks great either way!
