Jennifer looks so amazing in October's cover of Shape magazine. With her "all every ladies want" body, she also has the same insecurities all women have about their bodies.

"For the most part, yeah, 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?' That's when I say to myself, 'I look this way because I'm supposed to. If we all looked the same, we'd be boring.'"

So, what's the secret?

Jennifer shops to grocery every two days. She says, "Instead of piling up food in my fridge that says 'Come eat me!' I keep enough for only a couple of days." She also avoid keeps fattening treats around to avoid temptations from her late night cravings. She says, "What am I going to do? Drive out at 11 at night just to satisfy a craving? No, that's crazy."

She also doesn't skip her lunch. In her business, many women skip out in order to stay super skinny. But she opts for healthy choices like a salad with every meal, and lots of fruits and veggies. That's a good choice to keep healthy and stay in shape!

Exercise is also top on Jennifer's routine. She plays tennis and also enjoys running, even when she's traveling. While visiting Monaco with boyfriend Jamie Kennedy, they ran 40 minutes every morning through the streets of Monte Carlo. That's a great way to explore new places and burn calories too.

Jennifer takes care of her inner self too. At night, she says five things she finds sexy about herself, and says, "I fall asleep feeling beautiful. Then in the morning, before I leave the house, I say five things I love about myself . . . That way I can go out into the world with that little bit of extra confidence."
