Growing up in Brazil, Adriana De Moura fell in love with the ocean. Every weekend, she would frequent the beach, where she was entranced by sea creatures swimming in their natural habitat.

When PETA approached "The Real Housewives of Miami" star to appear in its new print-advertising campaign, she didn't think twice, even if it meant jumping into a bathtub naked.

The campaign features the Brazilian bombshell in the bath below the words, "Could you live in a tub for 40 years?" The ad protests what De Moura calls the incarceration of Lolita, an orca that was captured in 1970 and now lives in a tank at the Miami Seaquarium.

"Why do we have the right to capture a mammal?" De Moura asks. "They have their own language, feelings and social networks. But we incarcerate them to perform stupid, silly tricks day in and day out. … It's not right."

De Moura, an art curator, lives with her husband, interior designer Frederic Marq, and son, Alex, in a mansion on Hibiscus Island in Miami Beach. "Every morning, I meditate and look to see who's out there," she says. "I might see a pufferfish, or lizards. When I'm paddleboarding, I see dolphins and manatees. But I don't mess with them. I let them enjoy their natural habitat."

Relaxation is something De Moura can use right now, especially after filming Season 3 of "The Real Housewives." This season, as shown in the Bravo promos, De Moura gets married, goes head to head with her castmate Lea Black and is accused of being married to Marq since 2008.

Of her new nemesis Black, she says: "We had a strong friendship. But instead of jumping to my defense and trying to understand me, she just decided to cast the first stone. And I didn't appreciate it."

Fans of the franchise will get to see two weddings, as De Moura and model Joanna Krupa walk down the aisle — separately — on camera.

Since the two women didn't get along much last season, more drama will surely ensue. But as most reality stars like to tell reporters, De Moura says you'll have to tune in to find out.

"The Real Housewives of Miami" will premiere 9 p.m. Monday, Aug. 12, on Bravo.
