The Hunger Games star Jennifer Lawrence has definitely come a long way since her "tomboy" days back home on the farm in Kentucky, when she used to fish and play sports with her older brothers (she even played basketball on an all-boys team).

Although the self-deprecating 21-year-old calls herself a "troll" and admits she has the "worst self-esteem," she's excited to trade her sweatpants for Hollywood's glitzy gowns (like this red Marchesa dress and backless LBD by Tom Ford, both pictured above), saying, "I'm excited to be seen as sexy." The attention is definitely something Jennifer should get used to — especially considering The Hunger Games made $152.5 million in its opening weekend (more than any of the Twilight films, btw)! "I look at Kristen Stewart now and I think, 'I'd never want to be that famous.' I can't imagine how I'd feel if all of a sudden my life was pandemonium," admits Jennifer.

Sorry "girl on fire," it's too late now.
