Mary-Kate Olsen MKOLSEN083107_02.jpgWe've seen Mary-Kate wear all manner of interesting outfits - but apparently she saves her craziest getup for when we're not watching! According to a report in People, the rising starlet loves running around her house in the buff, albeit with a few jewels or a pair of heels to offset the ensemble. Apparently, the former Full House star barely even bothers to cover up when she's got company - she's quoted in the article as saying that "All my friends will tell you I love running around...naked with jewelry." How rude!
