The mother-to-be hasn't been shy about treating her Instagram followers to glimpses of her growing belly, and she did just that today when she shared a brand-new, bikini-clad selfie. "So far so good Apparently I've swallowed a bell pepper this week..." Prinsloo captioned the black-and-white shot, which shows her posing from the side in a strapless, scalloped two-piece and hat.
