Dianna Agron - Grammys 2011 Red Carpet

Dianna Agron walks the red carpet at the 2011 Grammy Awards held at the Staples Center on Sunday (February 13) in Los Angeles.

The 24-year-old actress 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.’” The award ended up going to Train for “Hey, Soul Sister.”

“We’re crashing the party … I’m crashing the party, I should say,” Dianna dished before the show about their nomination.

The day before, Dianna and her on- and off-screen beau Alex Pettyfer attended a fan meet-and-greet at Hot Topic.

FYI: Dianna is wearing a black silk satin bustier and matching skirt from Vivienne Westwood‘s Gold Label collection. She finished off her look with House of Lavande jewelry, a Judith Leiber bag, and black satin Ferragamo pumps.
