Emmy Rossum is a triple threat—she can act, sing and design handbags! Earlier this year, the Shameless star teamed up with Elie Tahari to create the “Emmy” bucket bag to raise funds for Safe Horizon and last night, Olivia Munn was on hand at Tahari’s New York City outpost to see Rossum unveil her fashion masterpiece. Also in N.Y.C. Alexa Chung stepped behind the decks to deejay for Jessica Szohr at the Sony Ericsson Xperia Play bash, while new mom Mariska Hargitay stopped by the Can-Do Awards to benefit the city’s Food Bank.
