WWHL host Andy Cohen asked the actress-singer to, once again, share some of her health and beauty favorites, and the star was happy to oblige. Lopez—who looked chic and sexy in a daring Andrew Gn dress—said that the one makeup product that she can't live without is lip gloss, and that the food she recommends for attaining better skin is oatmeal. When asked what she does to remove dark circles under her eyes, Lopez put it simply: "Sleep."

The American Idol judge also spilled her weight-loss regimens, and said that if she could only have one workout routine, it would be cardio. Watch Jennifer Lopez share her health and beauty tips on WWHL in the clip below:
