MODEL : Jessica Biel Takes The Plunge In Low-Cut Gown At Tiffany & Co. Event

Jessica Biel Takes The Plunge In Low-Cut Gown At Tiffany & Co. Event: Jessica Biel looked incredible as she walked the grey carpet at the 2014 Tiffany & Co. Blue Book Celebration on Thursday, April 10, at the Guggenheim Museum in New York City.

Fresh off her return from England -- she's been traveling with husband Justin Timberlake on his 20/20 Experience World Tour -- Biel wowed in a black Oscar de la Renta gown featuring a low-cut neckline, belt and thigh-high slit. She paired the dress with Christian Louboutin shoes and Tiffany & Co. jewelry.

Also at the event were stars Katie Holmes, Kate Bosworth and husband Michael Polish and Seth Meyers and his wife, Alexi Ashe. Timberlake was nowhere in sight, but his lady sure stole the show.
