The ladies donned their workout clothes, sticking strong to their strict work out regiment. Kim — OK!'s cover girl — lost 15 pounds by eating right and working out. She also launched her new fragrance, hitting Sephora in February. Khloé is busy getting busy with new hubby Lamar Odom. In a recent interview, Khloé revealed she's not rushing to have kids, but also "not doing anything to prevent it."
