Far be it from me to question anything related to some visual wonderments by one super fine female form like Joanna Krupa, but this casual nip slip bending over in Miami, well, if I didn't know any better, I'd say Joanna maybe kind of planned this one out. Which takes away nothing from the majestic sights provided by this Krupa nipple slip. I don't need to question motive when the answer is Joanna's bare boobtastic on display even just a peek.
In summary, nip slip, definitely. Wardrobe malfunction, hmm, the jury is still out. Enjoy.
