Calvin Harris reckons Sam Smith should pen a weight loss book

Many of our SHEmazing! readers were quite shocked by Sam Smith's drastic weight loss over the past few months. 

The talented singer has been on a strict diet and exercise regime since mid 2015 and the results have really begun to show over the past few months. 

While many fans have been divided by the drastic transformation of the Writing's On the Wall singer, it seems that one fellow Brit thinks the star's health kick is pretty amazing. 

Calvin Harris took to Twitter yesterday to congratulate the 23-year-old on his fitness and he even reckons that Sam could make money out of it.

"Sam smith weight loss is legendary he should write a book big up Sam smith," said the Scottish DJ, who has had quite the body transformation himself since he first hit the limelight. 

Calvin too went on a fitness kick that saw him land a Giorgio Armani underwear campaign.
