Butt seriously: a nude Bethenny Frankel will now greet tourists and New Yorkers on a giant billboard near Manhattan's Times Square. Emblazoned with the text "Fur? I'd Rather go Naked," the traffic-stopping ad (shot by photographer Joseph Cultice) is the latest from PETA, of which the Real Housewives of New York star is now a supporter.

Frankel gets bonus points, too: she was pregnant when the au naturel shot was taken. "It's so tasteful and beautifully done," she told the New York Post. "I am especially pleased because it doesn't look like there's been any airbrushing and I was already pregnant when I shot it."

The cookbook author and reality star -- who'll return for the third season of Real Housewives as well as star in her own Bravo series -- admits that she "used to wear fur" like her socialite friends. After she encountered a PETA protester holding a sign of a "skinned animal," however she changed her ways. "It made me sick. I felt disgusting," she says in a PETA statement. "I'm cleaning out my closets -- trim, everything. I don't see any reason for cruelty."

Frankel, 39, is now three months pregnant with her first child; the father is her boyfriend of over a year, Jason Hoppy.
