Anne Hathaway arrived looking the part of a princess in an ethereal Valentino gown to tonight's White Fairy Tale Love Ball in Crespieres, France. Olivia Palermo and her boyfriend, Johannes Huebl, also stepped out in their finest black-tie attire for the charity event benefiting the Naked Heart Foundation with proceeds going to underprivileged children in Russia. Earlier in the day Anne picked a chic black gown for a viewing of Valentino's Fall/Winter collection and later changed into a delicate white lace dress for a sightseeing tour through Paris with her boyfriend, Adam Shulman. Anne's attention is focused on fashion right now, but soon enough she'll return to her big-screen projects. Next month we'll see her making the promotional rounds on behalf of One Day while her other flick The Dark Knight Rises continues filming.
