Dianna Agron, Alex Pettyfer premiere 'I Am Number Four'
The "Glee" star's action flick also costars her beau, Alex Pettyfer. Throw the knockout Vivienne Westwood gown on top, and we're almost jealous.
Almost -- as plenty more exciting names turned up for on the red carpet for the screening at Mann's Village Theatre in Westwood.
DreamWorks honcho Steven Spielberg was in the house, as was producer Michael Bay, greeting "Four" supporting stars Teresa Palmer and Callan McAuliffe. (Click the pics to see more photos from the premiere.)
"Modern Family"'s Ariel Winter was the perfect little lady in a black cocktail dress, while "Tree of Life" actress Jessica Chastain and Amanda Michalka went for more adult evening wear.
"I Am Number Four" opens Feb. 18.
