jennifer lawrence embarrassed thighs catching fire dress Jennifer Lawrence embarrassed over her thighs in 'Catching Fire' premiere dress

Jennifer Lawrence went with a pretty daring look at the Los Angeles premiere of “The Hunger Games: Catching Fire.” Her Dior Haute Couture dress had a sheer shirt that showed off her legs, and it turns out she had any normal woman’s bout of self-consciousness when flaunting her physique.

“I think any time a girl has to show her thighs it’s never going to be her favorite look. I loved it, I loved the dress — if someone else wore it,” Lawrence tells “Good Morning America.” “It’s hard for any woman to look at a picture of herself and [like it].”

It probably didn’t help that Lawrence was also dealing with abdominal pains that ended up sending her to the hospital. She continued talking about her stomach troubles on “GMA,” saying that they might be more serious than it sounds.

“I was getting this really bad abdominal pains for like three weeks and I did that thing where I’m like, ‘I’m not gonna go to the doctor. And then, I finally had a day where I was like, ‘No, I need to get this looked at.’ Now it’s reported in the news that I went to the emergency room for gas, which is awesome. Let’s confirm that!” she says. “They’re saying it could either be in my lower intestine or all in my mind, so I’m gonna cross my fingers for it’s all in my mind and I’m just crazy.”

Of her new pixie cut, Lawrence claims she didn’t have an inspiration for the look. “I really don’t know,” she admits. “It was really impulsive. I was like, I’m cutting it! And it was just all gone. And now I look in the mirror and I’m like, yeah, it’s all gone!”

As for Lawrence being the prankster on the “Catching Fire” set, she says she’s actually “just mean to everybody.” Instead of pranks, the cast of “The Hunger Games” actually tends to just punch each other.

“They take it easy on me when we’re doing press tours because I have bare arms,” Lawrence quips.

Lawrence also opens up about the responsibilities she feels female celebrities have to their fans.

“We’re so responsible for this younger generation,” she says. “It’s teaching people who tot talk to each other and relate to each other. … Why can’t we just be nice? It’s like we grow up and go right back to high school.”

“The Hunger Games: Catching Fire” is due in theaters on Nov. 22.
