Dianna Agron looks stunning as she arrives at the 2011 Grammy Awards held at the Staples Center on Sunday (February 13) in Los Angeles.

The 24-year-old actress wore a black silk satin bustier and matching skirt from Vivienne Westwood’s Gold Label collection with House of Lavande jewelry and a Judith Leiber clutch.

Dianna and her Glee castmates were nominated for Best Pop Performance by a Duo or Group for their rendition of Journey’s “Don’t Stop Believin’.”
