Joanna Krupa of "The Real Housewives of Miami" hit the beach in Santa Monica, Calif., Tuesday in a bikini that caused two nip slips for the 33-year-old Polish model.

Krupa and her sister Marta relaxed on the beach, but it was "The Real Housewives of Miami" star who made ripples with her nipples. Photos of Krupa's double nip can be seen here and here.

Krupa showed off her tight body in a hot pink bikini, but her top hung low in two occurrences that led to a wardrobe malfunction.

The nip slips sparked skepticism, with the Huffington Post wondering if Krupa's wardrobe malfunction was staged.

The website wrote, "looking at these pictures, we have to question, the, uh, spontaneity of this alleged wardrobe malfunction. Was Krupa's rogue nipple merely a publicity tactic, drumming up attention for the new season of "Real Housewives?"

Krupa earlier told The Huffington Post that she has a third nipple.

"It looks more like a mole but my doctor said it's an actual third nipple," the Polish model said.

Kupa was born in Warsaw and raised in Chicago before she and Marta convinced their parents to move to Los Angeles so she can pursue a modeling career, according to her official website.

Krupa will be featured on the second season of "The Real Housewives of Miami," which airs Sept. 13 on Bravo.

As Krupa gets set for reality stardom, the Polish model is no stranger to celebrity. She's been named "Sexiest Top Model in the World," and was featured on E!'s "Sexiest People" episode in 2008.

Krupa has also graced the pages of Maxim and Playboy and is a spokeswoman for PETA, where she appeared nude in the animal rights group's "I'd Rather Go Naked Than Wear Fur" campaign.
