Khloe Kardashian recently debuted a svelte bikini body on the cover of Life & Style magazine, reportedly after dropping 20 pounds in 20 days. “My husband is working out four to six hours a day right now, so I work out with him,” the 27-year-old told the publication (husband is basketball star Lamar Odom). “We’ll do outside workouts and inside workouts. We’re always switching it up, so it’s fun.”
