That's one way to get Justin Timberlake's attention.

Jessica Biel turned heads in a white Giambattista Valli gown, which featured giant poufy sleeves and a sexy cut-out design at the Fashion Group International Night of the Stars bash in New York City on Thursday night.

The actress, 29, paired the daring couture look with a gold leaf belt and Fred Leighton jewels. The only thing she was missing was her on-again boyfriend.

On Wednesday the couple partied in the Big Apple with Elton John and David Furnish at Timberlake's restaurant Southern Hospitality for the One Night Only party. Biel was all smiles in a casual gray sweater, jeans and minimal makeup.
