STAGE TUBE: 'Mommy Wars' on Upcoming Episode of NBC's UP ALL NIGHT

On an upcoming episode of NBC's hit comedy UP ALL NIGHT entitled "Mommy Wars", sparks fly when Reagan gives Kayla's mom a piece of her mind. The sitcom airs Wednesday nights at 8/7 CT on the NBC network.

"Up All Night," is created by Emily Spivey (NBC's "Parks and Recreation" and "Saturday Night Live") and executive produced by Lorne Michaels (NBC's "Saturday Night Live" and "30 Rock"), 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 cliches 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.
