About Sookie...
Sookie St. James Mellville is a fictional character on the television series Gilmore Girls, played by Melissa McCarthy.

Sookie is a warm, kind-hearted, clumsy, ditzy, brilliant chef, who has control issues when it comes to her food. She has an (apparently completely deserved) stellar national reputation, which makes one wonder why she's putzing around in little Connecticut inns, but it does help to make her one of the few people Emily Gilmore likes.

She married Jackson Melville (whose name occasionally changes to Belleville — reason unexplained), her produce supplier, (Season 2, Ep. 22 - I Can't Get Started) and they have two children: Davey (Born at the end of Season 4, Ep 7 - The Festival of Living Art) and Martha, middle name Janice-Lori-Ethan-Rupert-Glenda-Carson-Daisy-Danny. (Born Season 5, Ep. 21 - Blame Booze And Melville). She and Jackson chose to have an evil creepy midwife and a home birth for Davey, but went to the hospital for the next birth. She and her family live in the house she owned before she started dating Jackson.

Sookie and Lorelai co-owned and operated the Independence catering company to earn money to help fund renovations on the Dragonfly Inn after the Independence Inn burned down (Season 3, Ep. 17 - A Tale of Poes and Fire).

Alex Borstein, Jackson's real-life wife, was originally cast in the role of Sookie St. James, but had to back out due to scheduling conflicts. Instead, she has taken miscellaneous supporting roles throughout the show, including Drella, the harpist from Season 1, and Miss Celine in Season 5.
