After years of flaunting her coke-bottle curves, Kim Kardashian now has a new bump to be proud of. The mom-to-be is putting health first by engaging in cardio-ballet workouts with trainer Tracy Anderson to stay in shape during her pregnancy. "It’s really important for me to have a fitness routine that works for my body and my schedule, and I’m really happy with the workout plan Tracy is working with me on," blogged Kim on her Celebuzz site. Anderson also helped Kim's sister, Kourtney, lose 44 pounds just six months after she gave birth to her second child thanks to 90-minute dance-focused workouts.
