JENNIFER LOPEZ

The actress and singer formerly known as J.Lo has a more mellow lifestyle as Mrs. Marc Anthony, the happy homebody who watches Grey's Anatomy and American Idol with Anthony, 38. In keeping with the laid-back vibe, Lopez, who describes her look as "classic at times, rock and roll, earthy and feminine at others," has one straightforward beauty goal: "I like to look good for Marc," she says. As for her beauty routine? "I don't use a lot of expensive creams," says Lopez, 37. "It's more simple: mild cleanser, sunscreen and lots of water."

DON'T: GET A FRUIT ACID PEEL
After trying one a few years back, "I looked like I went bobbing for apples in a volcano. I feel comfortable now knowing that's just not my thing."
