Victoria Beckham celebrated her 35th birthday with a ladies-only dinner Wednesday night.
Also there to celebrate the former Spice Girl: Kate Beckinsale, who arrived alone, followed by Jennifer Lopez.
Nicole Richie joined the group later.
"There was a lot of laughing and giggling, and, at one point, I saw all of them making a toast and cheering with their classes," an onlooker tells Usmagazine.com.
After a champagne-filled dinner, the waiter brought over a cake "and the ladies sang Happy Birthday to Victoria and she smiled and blew out her candle," the witness adds.
They all left around 1 a.m.
