STAGE TUBE: Sneak Peek - A Game of Trivia on Tonight's UP ALL NIGHT on NBC

On tonight's episode of NBC's UP ALL NIGHT entitled 'New Year's Eve', Reagan's (Christina Applegate) extreme competiveness comes out at a New Year's Eve game night, much to Chris's (Will Arnett) embarrassment. Meanwhile, Kevin (guest star Jason Lee) worries that Ava (Maya Rudolph) is ashamed of him and Missy (Jennifer Hall) brings an unexpected date to the party.

UP ALL NIGHT is an irreverent look at modern parenthood. Christina Applegate ("Samantha Who?") stars as Reagan Brinkley: loving wife, successful career woman, life of the party and, most recently, mom. Determined not to compromise her career or cool reputation to the clichés of motherhood, Reagan adjusts to life with a baby and returns to work with the support of her stay-at-home husband, Chris (Will Arnett, "Arrested Development"). As Reagan and Chris figure out their new life, self-doubt, sleep deprivation and the pressure of today's parenting protocols rattle their confidence. What's more, the endless needs of Reagan's boss, ambitious but vulnerable talk-show host Ava (Maya Rudolph, "Saturday Night Live," "Bridesmaids"), threaten to throw Reagan off balance.

UP ALL NIGHT airs Thursdays at 9:30 pm/ET on the NBC network.
