Emmy Rossum had some useful advice when we asked her about weird experiences with animals at last night’s Wildlife Conservation Society Spring Gala at the Central Park Zoo. “When I was 7, I went to Alaska on vacation with my mom for a month and came this close to a bear,” she said, indicating a few short inches. “They had told me, if you ever see a bear in the wilderness, sing to it, because it somehow can identify that you’re a human. Don’t whistle because it will think you’re a bird and it’ll eat you. But if you sing to it, apparently, it’s pacified and it walks away. So I sang ‘Somewhere Over the Rainbow,’ and it walked away. Did a little Judy Garland rendition and he sauntered off.”
