Single working mom Christine Campbell has just learned that her ex is dating a much younger woman with the same first name. To avoid any confusion, the new girlfriend is dubbed New Christine, which leaves her with the un-fortunate nickname Old Christine. Julia Louis-Dreyfus' hilarious and insightful performance in the title role won fans and earned her the 2006 Emmy as Outstanding Lead Actress in a Comedy Series. Christine struggles to hold it together as she adjusts to her new nickname, confronts the meanie moms at her son's private school, jumps back in the dating pool -- and gets laughs every misstep of the way.
