Emmy Rossum is an obvious "Crush of the Day." The multi-talented actress and singer has a girl-next-door sexiness.. if the girl-next-door had a role in a Showtime TV series ("Shameless") that allowed her to get naked on screen every week.

You may know Emmy from her role in "The Day After Tomorrow" or "Phantom of the Opera," - which you better have seen while on a movie-date. Rossum is known for her interview candor, beaming smile and near-perfect skin, which you'll be able to see a lot of on "Shameless."

And she can sing, as she proved on "Conan" earlier this month when she crooned opera for a wiener.
