When I think of Julia Louis Dreyfus, lots of things come to mind. Aside from having a winning smile, she's funny and quirky on her current show, "The New Adventures of Old Christine," and man, does she ever have some great hair. And who can forget her "Seinfeld" character Elaine's ridiculous dancing skills (if you can call them that)?

However, it turns out that, at 48 years old (yes, really, 48), Julia can include wicked sexy and in shape to her list of attributes. She's on the April cover of "Shape" magazine, and girlfriend is stunning in a bikini top and cardigan. (By the way, does anyone ever actually wear a cardigan over a bikini top? Because, I never see it in real life, but I'm kind of digging it.)

What's even better is that she's truly earned that body. She hasn't been nipped or tucked, and she doesn't have plans to go under the knife any time soon, saying, "Of course if things start to fall, I may have to do something to pull it all up. But seriously, the whole idea scares me. My mom never had it done and she looks fantastic. Hopefully I'll follow in her footsteps." Plus, her husband is totally against the idea, which always makes a bit of difference.

Don't think for a second, though, that Julia looks this good by accident. She's always looking for the best way to stay in shape, and says, "Unfortunately, I have to work at not being fat. I'm always trying different things to see what sticks." Umm, yeah. That sounds awfully familiar.

So what does she do? For one, she always eats breakfast -- her current favorite is two eggs, fried in olive oil, with a slice of whole-wheat toast with honey. Also, she makes sure to incorporate lots of local veggies into her diet.

Julia also loves sweets -- she even has a chocolate drawer! -- but she keeps her weight in check by working out consistently. "In a perfect world, I'd do it five times a week. Honestly, though, it's less than that," she told "Shape." But, she also knows that if she misses a few workouts, she really starts to crave it. No wonder her chocolate cravings don't pack on the pounds!
