The film's star Lea Michele, 25, opted for a nude embellished Valentino gown with a daring plunging neckline. She wore her hair in glossy side-swept waves and accessorized with Christian Louboutin shoes and Neil Lane jewels.

"Thank you to my amazing glam team @marktownsend1 and @melaniemakeup @EsteeStanley I love you guys!!!!!!" She tweeted to her hairstylist, makeup artist and stylist for helping her prep.

Fergie, who attended the premiere to support her hubby Josh Duhamel, dazzled in a silver strapless Monique Lhuillier dress with Christian Louboutin heels and Tiffany & Co. diamond studs. The 36-year-old singer also styled her hair in side-parted waves and rocked red lips.

Sofia Vergara enhanced her killer curves in a bustier-style black dress. The Modern Family star, 39, accessorized with a bright red clutch and wore her super-long hair in soft curls.
