Now, there's a kick in the self-confidence: 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, everyone calls one woman New Christine and the other Old Christine. You can guess which is which.

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 with a post-bikini bod and gets laughs every misstep of the way. You go, old girl!
