That's my advice should you ever bump into Emmy Rossum, the smashingly beautiful young actress and vocal powerhouse who stars as Christine, the tormented soprano, in the new film adaptation of Andrew Lloyd Webber's Gothic romance cum musical extravaganza The Phantom of the Opera, which will invade the national consciousness on December 22.

Just keep telling yourself she's only 18. One would be wrong, who can tell you she's ready for her close-up and then some. One might guess that 18-year-old Emmy Rossum, the classically trained singer who stars in the new Phantom Of The Opera movie, is soft and demure. We're betting she'll have to get used to it. However, no young lady, however professional, can truly escape the power of princess chic: The on-the-verge actress was sweetly enchanted by the fairy-tale frocks hand-picked for her by the ELLE team and age-appropriately awed by the array of delicate, feminine jewelry. Dressed in a long black coat and jeans, with hair swept back in a sleek ponytail and the obligatory sunglasses in place, Rossum was definitely ready for her close-up.

18-year-old Emmy Rossum (Phantom of the Opera) is still in the newly-minted category when is comes to celebrity, but that didn't stop her from looking every inch the star upon arrival at her first big cover shoot for ELLE in New York City.
