Gisele Bundchen donned a burqa to evade the paparazzi. Offensive to Muslims or a reasonable attempt at privacy?

Model Gisele Bundchen put on a burqa to conceal her identity during her trip to the plastic surgeon in Paris. Hoping to evade the paparazzi, Bundchen was nontheless discovered by the photographers who noticed her longtime chaffeur. Bundchen and her sister were both dressed in burqas, but quite evidently did not research enough about Muslim culture as their feet were visible in their open-toed sandals - shoes that strict Muslim women are prohibited to wear. Do you think that Bundchen’s actions are offensive to Muslims or a reasonable attempt at privacy?
