"The Real Housewives of Miami" Star Joanna Krupa is up her dirty antics once again. The actress was seen wearing a sheer gown for Human Society of the United States 60th Anniversary Benefit. Krupa's butt and nipples were on full display and she did not mind posing for the shutterbugs in a risqué outfit.

The 34-year-old opted the gown designed by former Project Runway star, Michael Costello. Krupa coupled her look with a neatly tied high pony, minimal accessories and nude make-up. She did look stunning in a figure hugging, mermaid fit gown but it was too over the top for a Human society event.

However, this is not the first time that Krupa had taken a risk with her outfit. On Nov. 16 she went braless in a flimsy top and showed her boobs with much aplomb.

Regarding her dress Kurpa took to twitter and stated, "It's unfortunate that the flashes ruined the look of this gorgeous Michael Costello gown and made it look sheer. Even though my dress was a bit ruined by flash at least I m not leaving a place drunk with a tampon string hanging."

By stating the drunk episode Kurpa was her referencing to her "RHOBH" arch-nemisis, Brandi Glanville.

Apparently, Krupa wishes to join "RHOBH" and in her interview to "Life & Style" she said that if she gets a chance to she would love to be a part of "RHOBH".

"If the opportunity came and Miami wasn't happening, then I definitely wouldn't say no. I'd think about it and see.I do have some friends from there. It's not something I was approached or talked to about," she explained to the mag at the The Humane Society's 60th Anniversary Benefit Gala in Beverly Hills. "[Rumors started] because I have girlfriends from there.

Let us know what do you think about Krupa's nipple reveal in a public event. Do you think it her dress was appropriate?
