Britney Spears – 20 lbs

Britney Spears is yet again another celebrity who has given birth twice. Often dubbed as the “Princess of Pop,” Spears has lost around 20 pounds in total over the years. According to Hola!, sticking to a diet heavily based on fruits and vegetables and participating in physical activities are what have helped her stay in shape all these years.

Now aged 39, the Oops!… I Did It Again singer has released nine albums and over 45 singles as of today. Unsurprisingly, most of it has made it to the US Billboard Charts, with many even peaking at number one.
