Kristen Wiig and Amy Poehler were hanging out in the VIP lounge around 6:45 p.m when Rudolph walked in, an attendee tells Us Weekly. "Kristin jumped up and yelled 'Where the f-ck have you been, bitch? I've been waiting for you!'" The comedic trio "were like a scene out of Bridesmaids, clearly giddy and happy to see each other," the observer adds.
Rudolph also chatted up Saturday Night Live creator/producer Lorne Michaels and Academy Award nominee Anne Hathaway. "Anne approached Maya for a hug," the attendee says. "Even though there was a flurry of people around them, Anne and Maya spent a while standing in the middle of the ballroom talking only to each other."
Later that evening, Rudolph and Poehler appeared on stage to introduce Steve Martin, who presented the Distinguished Collaborator Award to Michaels. "Maya and Amy stood on the stage whispering to each other," the attendee tells Us. "Maya held her belly while she cracked up."
Rudolph and The Master's Anderson (who did not attend the event) are already parents to Pearl, 7, Lucille, 3, and Jack, 19 months. "Before I had [Pearl], my job at Saturday Night Live was my everything. It was my husband, it was my children, it was my love," the Away We Go actress told TIME in 2012. "I used to take so many things seriously, like 'What do you mean he didn't do the fart joke? Why not?' Children sort of allow you to only have room for important things in your brain."
