Pregnant Gisele Bündchen Wears Bikini in David Yurman Campaign Film

Baby on board? Big deal!

Supermodel mama Gisele Bündchen didn't let her second pregnancy get in the way of shooting a moody, beach-set video for jeweler David Yurman's Fall 2012 campaign shot by Peter Lindbergh

Shot in black and white alongside crashing waves and a wild horse, the Brazilian beauty shows off just the slightest hint of a baby bump as she models the designer's diamond sparklers, layered necklaces, statement rings, and stacks of silver Cable Classics bracelets.

She even poses in a skimpy crochet bikini top, though the camera avoids showing her stomach. Heck, if we didn't know better, we'd be none the wiser about Baby Brady #2. Thank goodness for that pesky paparazzi, right?
