Jennifer Lawrence covers the December 2013 issue of InStyle where she said that absolutely nothing can motivate her to work out.

"During Hunger Games when I was eating ungodly amounts, I used to tell myself, Stop eating - people are going to see this. This is going to be around forever," she said. "But nope! I was like, I still want candy, and I still want a hot dog! And then X-Men started and I thought, Oh, definitely - I'll be naked, I'll make myself work out and diet. But nope. Not me!"

The actress also explained that growing up with two brothers - Blaine Lawrence and Ben Lawrence - is a big reason for her tough skin.

"My brothers and I would scream at each other and we'd be like, 'I hate you! You're stupid! You're ugly!' And then five minutes later it would be, 'I love you,'" she said. "I got thrown down stairs, I got punched. It's not like I had a superior childhood because I had brothers - I was crying just as much."

Yet, the 23-year-old recently opened up about how hurt she felt after she was criticized for her weight when she was younger.

"I was young. It was just the kind of s--t that actresses have to go through," she told U.K.'s Harper's Bazaar in the November 2013 issue. "Somebody told me I was fat, that I was going to get fired if I didn't lose a certain amount of weight."

The 23-year-old actress also recalled being given photos as her "motivation" to lose weight. While she said some people believe that the incident shouldn't bother her anymore, especially because of her professional success, the Oscar-winner is still affected by it.

"I was a little girl," she said. "It doesn't matter what accolades you get. I know it'll never happen to me again. If anybody even tries to whisper the word 'diet', I'm like, 'You can go f--k yourself.'"
