Jessica Biel Has a Fun Girls' Night Out With Reese Witherspoon, Diane Kruger, and Naomi Watts

Talk about a girls' night out! On Friday night, Jessica Biel made her way to Tiffany & Co.'s annual Blue Book dinner party in NYC, where she met up with pals Naomi Watts, Reese Witherspoon, and Diane Kruger. On top of striking a slew of gorgeous poses alongside the other ladies, Jessica, who arrived without husband Justin Timberlake, couldn't help gushing over her other half and son Silas to People, saying, "They're like the same person. It's like a mini version of him. They like to sit and watch golf together. The only TV that Silas is allowed to watch is the Golf Channel, which is really funny."

Just a day before, Jessica and Justin attended the NYC premiere of The Devil and the Deep Blue Sea, where the two drew eyes with their cute PDA on the red carpet. Keep reading for more pictures, and then check out the most precious photos of baby Silas.
