Talk about a girls' night out! On Friday night, Jessica Biel [1] made her way to Tiffany & Co.'s annual Blue Book dinner party in NYC, where she met up with pals Naomi Watts [2], Reese Witherspoon [3], and Diane Kruger [4]. On top of striking a slew of gorgeous poses alongside the other ladies, Jessica, who arrived without husband Justin Timberlake [5], couldn't help gushing over her other half and son Silas [6] 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 [7], 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 [8].
