Celeb Pregger Pounds (PHOTOS); Beyonce gained 50 pounds in pregnancy. Sometimes it seems that all celebrities are magically blessed with amazing weight loss powers allowing them to wear their skinny jeans only weeks after giving birth.

The truth is that many celebrities hire trainers, nutritionists, and full-time nannies to help get their bodies in shape real quick.

One effortless way is to breastfeed. Women burn 500 calories a day producing breast milk while breastfeeding.

Kerri Russell, Nicelle Herrington, Model Camila Alves, Gwyneth Paltrow & Debra Messing ALL credit breastfeeding to most of their post-pregnancy weight loss.  

Beyonce "barely recognised" herself as she checked into the hospital to give birth to her baby girl - because she had gained so much weight during her pregnancy. The pop superstar packed on 50 pounds (22.68 kilograms) while carrying daughter Blue Ivy.
