"I remember when I was 13 and it was cool to pretend to have an eating disorder because there were rumors that Lindsay Lohan and Nicole Richie were anorexic. I thought it was crazy," Jennifer tells the mag. "I went home and told my mom, 'Nobody's eating bread -- I just had to finish everyone's burgers.'"

Jen added that she's "so sick of these young girls with diets ... I think it's really important for girls to have people to look up to and to feel good about themselves."

So what does she do when she's not working? "I love to just hang out with my friends and watch Real Housewives," she says. "My favorite cast used to be New Jersey, but now I'm really into Beverly Hills."

Jen also chats about her co-stars Josh Hutcherson and Liam Hemsworth, telling the mag, "Josh and Liam are really great friends, too. They are hilarious and sweet. They are like my brothers. As soon as we all got together, we reverted back to being 13-year-olds," she says. "Josh and I were neighbors. Every time I would come in late, I would go and bang on the door and wake him up and we'd all hang out."

The flick hits theaters March 26 ... can't wait!
