Christina Applegate and her Up All Night costars Will Arnett and Maya Rudolph got silly on the press line last night in LA at the Paley Center for Media. The trio was on hand for a panel about their NBC comedy, during which Christina said that, as a working mom herself, she feels like she's living the same life as her character! The cast also hinted that a second baby might be something that comes up as a possibility for Will and Christina's onscreen couple in the next season of the series. Will was back in LA for the event after hitting up the Met Gala with his wife Amy Poehler on Monday evening. She wore a gown by Fotini, and he sported a tux by Calvin Klein — check out all the pictures from the Met Gala in our gallery!
