Pics: Did she get breast implants? Gisele Bundchen finally slips into a bikini

This is the first time the 35-year-old Brazilian supermodel has slipped into a two piece since it was reported she went undercover in a burka in July to get a secret breast enhancement operation while in Paris. Left is a photo from her time at the beach with her kids last weekend, and right is a few years ago. See any difference? The mother of two allegedly had the surgical procedure after complaining that her breast had 'sagged' following her two pregnancies. It reportedly cost $11,000, and was a 35th birthday and retirement from runway modeling present to herself. See more photos after the cut...
