Real Housewives of Miami star Adriana de Moura is going to strip down for a good cause. The Brazilian bombshell will pose au natural in an upcoming advertisement for PETA.

She will be 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.

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 this week.

De Moura is also prepping for the season three premiere of Real Housewives of Miami, which will air on Bravo Aug. 12, at 9 p.m.

This season revolves heavily around both De Moura and Joanna Krupa planning their dream weddings.

In an exclusive interview with E! News, Adriana revealed that there was actually a causality of the wedding war.

"There was drama because we had one bridesmaid in common, Lisa Hochstein," shesaid. "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."

 Who had the more fabulous wedding? "Personally, I think I won," Adriana said.
