Adriana De Moura is stripping down for a good cause. 

E! News has exclusively learned that the Real Housewives of Miami star will pose nude for PETA, appearing entirely naked in a bathtub for a provocative new ad which aims to bring awareness to the controversial practice of keeping marine mammals in captivity for entertainment purposes.

De Moura's ad will ask, "Could you live in a tub for 40 years?" and will highlight the life of Lolita, a lone orca who has been imprisoned in a small tank at the Miami Seaquarium after being captured in 1970.

The campaign is particularly close to the Bravo star's heart, as the brunette beauty hails from Brazil, one of the few countries that has completely banned the contentious practice, and De Moura hopes the United States will follow her native country's lead.

She also posed for her eye-catching PETA ad in order to encourage Miami Seaquarium to release Lolita from confinement into a coastal sanctuary.

E! News will have an exclusive behind the scenes look at Adriana's nude PETA campaign shoot next week.

In addition to her work with the animal rights organization, De Moura is prepping for the season-three premiere of Real Housewives of Miami, which will air on Bravo Aug. 12, at 9 p.m.

If you've taken a peek at our exclusive promos, then you know this season revolves heavily around Adriana and Joanna Krupa both planning their dream weddings...while trying to out-fabulous each other (natch).

And in an exclusive chat with E! News, Adriana revealed there was even a causality in the wedding war.

"There was drama because we had one bridesmaid in common, Lisa Hochstein," she told E! News. "And I was like, 'Don't you go playing double agent!' At one point, because she was in my wedding, Joanna kicked her out of hers."

While De Moura says she and Joana have since buried the hatchet, the Brazilian beauty didn't have any problem sounding off on who had the better I-Do's.

"Personally, I think I won," she confessed. 

Can't wait to see all the drama go down!
