According to the mag, Parker was the "least sexy woman in a group of very unsexy women" that ironically starred in a show with the word "sex" in the title.
Coming in number second on the list was British singer Amy Winehouse thanks to her "hemorrhaging translucent skin, rat's nest mane and lashes that look more like surgically attached bats", reports the Sydney Morning Herald.
Third spot went to 'Grey's Anatomy' star Sandra Oh at No. 3 for her "cold bedside manner and boyish figure".
The top five was rounded off by pop star Madonna and Britney Spears who came in fourth and fifth place respectively.
Madge came in at No. 4 spot for her "self-righteous bellyaching and rapid postnuptial deterioration."
Britney was at No. 5 for "losing the ability to perform" as well as the fact that she has two children, two ex-husbands and has out on weight.
The top five list for Maxim Magazine's list of the world's unsexiest women is:
1. Sarah Jessica Parker
2. Amy Winehouse
3. Sandra Oh
5. Britney Spears (ANI)
