Jessica Biel & Justin Timberlake - Met Ball 2012

Jessica Biel and fiance Justin Timberlake walk arm and arm at the 2012 Met Ball held at the Metropolitan Museum of Art on Monday (May 7) in New York City.

The 30-year-old actress looked stunning in Prada – shoes, clutch, and an ivory double stretch satin deep-V gown with cascading jade green stones. She also sparkled in Lorraine Schwartz earrings.

Justin, 31, wore a black Tom Ford tuxedo with a satin shawl lapel, evening shirt, satin bowtie, cufflinks and leather “Chelsea” boots.

Earlier in the day, Jess was spotted running errands in the Big Apple sans Justin!

This year’s Costume Institute Gala Benefit – celebrating the opening of the Schiaparelli and Prada: Impossible Conversations exhibition – is co-chaired by Carey Mulligan, Vogue editor Anna Wintour, and designer Miuccia Prada.
