Jennifer Lawrence is ready for fans to see her as the tough and gritty Katniss Everdeen in “The Hunger Games” - but first, she’s showing off a much sexier side in Glamour magazine.

Clutching Katniss’ famous bow, Lawrence flaunts some serious cleavage on both the cover and inside the mag’s April issue … where she talks about getting in shape for the movie…

“I hate saying, ‘I like exercising.’ I want to punch people who say that in the face. But it’s nice being in shape for a movie, because they basically do it all for you. It’s like, ‘Here’s your trainer. This is what you can eat.’

She adds, “I don’t diet. I do exercise! But I don’t diet. You can’t work when you’re hungry, you know?”

Lawrence also addresses life in the public eye - telling the mag :

“In some ways, it’s a hard life, but it’s a great professional life. I’m doing what I love, and then I get months and months of rest. I have a lot of money for a 21-year-old. I can’t stand it when actors complain.”

With fame comes lots of attention and, let’s face it, money! Since she can pretty much spend her hard-earned cash however she wants, Lawrence explained to Glamour that sticking her fingers in the hotel minibar was an exciting moment for her!

“Just recently I started letting myself eat things from the minibar. When we were kids, we would never open the minibar,” she said. “A $6 Snickers bar? But the other day I was in a hotel and I was staring at a Snickers bar, and I finally just ate it. Then it was like something in me snapped. I opened all these drinks. I thought: I can do it now. Now I’m all grown-up. I can eat things from the minibar.”

We can’t wait to see Jennifer as Katniss Everdeen in less than a month!
