A pregnant model whose sexy selfies have turned her into an overnight internet sensation has snapped yet another another lingerie-clad photo of herself flaunting a barely-there baby bump - just 10 days before she is due to give birth. Sarah Stage, a 30-year-old underwear model and animal rights activist from Los Angeles, has documented her changing figure via her Instagram page throughout her pregnancy, earning herself a huge number of fans - as well as a fair share of critics - in the process. Although the mother-to-be came under fire last month as more and more critics spoke out against her unusually trim and toned figure, claiming it could be doing damage to her unborn child, their comments haven't stopped the model from sharing numerous photos of her tight abs with her 1.5 million Instagram followers.
