Played by Maya Rudolph
Maya Rudolph stars as Ava, Reagan's (Christina Applegate) boss, an ambitious but vulnerable talk show host, on NBC's new comedy "Up All Night."
Rudolph is most widely known for her turn on NBC's "Saturday Night Live," where she was one of the show's regular players for over seven years. Since her debut in 2000, Rudolph's memorably skewed portrayals include Oprah Winfrey, Donatella Versace and Whitney Houston, and such recurring sketches as "Wake Up Wakefield" and "Bronx Beat."
Rudolph can currently be seen in Paul Feig's hit comedy "Bridesmaids" opposite Kristen Wiig, Rose Byrne, Jon Hamm and Ellie Kemper.
