Jessica Biel went for a classy and understated black Tom Ford dress to last night's TIME 100 gala celebrating the 100 most influential people in the world.
The actress was accompanied by her smart suited husband Justin Timberlake at the swanky event held at the Lincoln Center in New York City.
The gala celebrates TIME magazine’s 100 most influential people in the world, and this year included Justin who was listed as an icon.
Jessica honoured her husband's friendship with fashion designer Tom Ford by sporting the demure and ladylike creation from his label.
The black open toed heeled sandals were also Tom Ford, as was her bag. Jessica finished off her look with jewellery by Lorraine Schwartz and a relaxed half up and half down hair style.
Christina Aguilera was also a lady in black, opting for a formal Victoria Beckham dress, Christian Louboutin shoes, and Lorraine Schwartz jewels.
Christina performed at the event, belting out hits At Last, Beautiful and Lady Marmalade to the assembled influential people.
Actress Olivia Munn looked stunning dressed in a yellow Michael Kors dress on the red carpet. The beauty completed her look with Jimmy Choo shoes, Smythson of Bond Street clutch, and a Lorraine Schwartz cuff.
The 32-year-old was joined at the event by designer Michael Kors himself and comedienne Amy Poehler.
Also in attendance at the prestigious event was Girls star Lena Dunham, who made it into TIME's top 100 list this year.
Lena posed on the red carpet dressed in a Saint Laurent number and posed with actress Claire Danes for photos.
Claire - who wrote Lena's profile for the magazine this year - went for a Lanvin dress, shoes, and jewels.
