It's no secret that Joanna Krupa loves to take it off now and again—but now she's baring all in the name of her favorite cause: animal rescue.

How to Watch

Watch The Real Housewives of Miami on Peacock and the Bravo App.

The model sat down with E! News to offer a first look at her new 2014 calendar, which will benefit her charity Angels for Animals Rescue. (Watch a clip of her shoot below.) Though Joanna has had a successful modeling career, she says she's a bit more self-conscious about "cellulite" these days, although judging by the video, she doesn't have anything to worry about. As for her motivation to take it all off, it's simple: "Sex sells."

On a more revealing note, Joanna also opened up about her marriage to Romain Zago. And she shares that filming the Real Housewives of Miami actually helped her marriage. "It definitely could put pressure, but for us, it saved our relationship," she told E! News. "I think if it wasn't for The Real Housewives of Miami I think we would've broken up last year. Because, you know, we've been together so many years, we've been engaged so many years, so we were basically living like a married couple. You take each other for granted. When we started filming, [we] had to talk about things we'd normally keep inside. For me, and I'm sure Romain will agree, [it] was more of a therapy for us, filming the show."

Do you think Joanna and Romain are the real deal? Will their marriage stand the test of time and reality TV? Let us know in the comments.
