Apparently there is a common (and great) belief, that if you are in Brazil, you should abandon the traditional swimwear and put on a thong. If these pics were taken in America, they would definitely be just hot bikini pics, but since they were taken in Brazil, we are thrilled to know that Fergie has taken part in Brazilian tradition and rocked a thong on the beach, giving us some of the most asstastic shots ever.
Maybe the best part is that her husband, actor Josh Duhamel, was right there and happily watching his wife flaunt her ass for all of us to see. Fergie has been said to have one of the best beach bodies in Hollywood, and her ass has to rank up there as one of the best we've featured on this site. We commend Fergie for taking part in a country's tradition, and reminding us why thongs were one of the best inventions....ever.
