Hunger Games star Jennifer Lawrence has some pretty down-to-earth opinions about Hollywood and the whole "fame" thing. She opens up about that -- and so much more -- in the April issue of Glamour.

Jennifer says that she gave herself three days to decide whether she was going to take the role of Katniss in The Hunger Games because she knew that her life would change in a big way if she did. "I knew from reading the books that I loved The Hunger Games," she says. "I just didn't know if it was worth changing my life for... I wanted to make sure that when I said yes, I wouldn't regret it. And I don't regret it. I would have said no because I was scared, and then I would have been that bitter actress telling my grandkids, 'I'm the one that turned it down.'"

She's also very open about things she loves about acting as well as the things she sees a lot of in Hollywood but doesn't particularly like. "[Acting] is a great professional life," she says. "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." Neither can we, but it's so refreshing to hear it from someone actually in Hollywood! It's like that line from Ben Folds' song "One Down": I'm really not complaining, I realize it's just a job. And I hate hearing bellyaching rockstars whine and sob.

As for how Jennifer feels about the pressure to stay in shape, especially now that we know about her love for Snickers bars? "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 says that while she does exercise, she doesn't diet. "You can't work when you're hungry, you know?"

We do know, Jennifer! And we thank you for being so honest about it!
