Jennifer Love Hewitt

Just because she has killer curves doesn't mean actress Jennifer Love Hewitt doesn't have her insecurities. "I'm a girl, after all," the 30-year-old tells Shape magazine. "For the most part, yea, I'm happy with my body, but there are days when I'm like, 'Ugh, Really? Why is it so hard to fit into my jeans?' But the "Ghost Whisperer" star still tries to keep a positive and healthy attitude about her curves: "I look this way because I'm supposed to. If we all looked the same, we'd be boring." No stranger to the pressures of Hollywood body image, the actress was once slammed for being too voluptuous, until she shed 18 pounds.  "Hollywood used to revolve around women with curves, like Liz Taylor and Marilyn Monroe," she tells Shape. "But not it's so different. Not that long ago, I went to this celebrity luncheon, and I was the only person in the room eating. The other girls looked at me like I hadn't gotten the memo, but I was hungry! All of these girls were afraid that if someone saw them eating, it would be a disaster. It makes no sense at all." <a href="http://www.shape.com/lifestyle/jennifer_love_hewitt_share_her_helathy_eating_secrets">Click here to read Jen's tips for keeping fit at Shape.com.</a> <b>MORE FUN STUFF FROM SHAPE: </b> <a href="http://www.shape.com/healthy_eating/healthy_eating_at_sporting_events">How to Eat Healthy at the Ballpark</a> <a href="http://www.shape.com/beauty_and_style/8_steps_to_fuller_sexier_hair">Eight Steps to Fuller, Sexier Hair</a> Click on to see more Jennifer Love Hewitt photos.
