Hilary Duff - Metropolitan Museum of Art Gala Arrival

Hilary Duff proved that she was A Grown-Up too, in this uber-sparkling, uber-beaded silver strapless gown by Elie Saab.

The “So Yesterday” singer was looking fine in a strapless silver beaded gown with matching clutch and earrings as she made her way into the Metropolitan Museum of Art in New York City.

And Duff was sporting another important accessory- arm candy. Her hottie hockey player boyfriend Mike Comrie was dressed to kill in a classic black tuxedo.
