#18 – Christina Aguilera
This hot-blooded and charismatic singer always had ups and downs when it comes to weight. One year, she was all curvy and overweight and the other year she was all slim and slender. However, it was the year 2013 when Christina definitely decided to get fit and keep her slim figure intact.
Today Christina has the body of a goddess albeit she has two childbirths behind herself and a stressful job. Keep up with the good work Christina!
