AskMen.com has released its annual list of the 99 Most Desirable Women in the World.  And this year's big winner is "Hunger Games" minx JENNIFER LAWRENCE.

--The website says, quote, "Overall, there's a sense that she's a little more authentic than other actors.  She's fresh because we haven't seen her all over the gossip pages for the past three or four years."  Jennifer was 47th last year.

--On the other end of the spectrum is KIM KARDASHIAN . . . who dropped 90 PLACES . . . from #8 last year to #98 this year.  The site says, quote, "She is petering off and basically dropping off the list at this point even as she's become more visible."

--SCARLETT JOHANSSON also took a hard drop . . . from #7 to #45.

--Meanwhile, infidelity seems to have HELPED KRISTEN STEWART.  She was 27th last year . . . this year she made it to #7.  And thanks to "Homeland", CLAIRE DANES made the list for the first time this year.  She's 20th.
