OLLY MURS, 35, is a singer and coach on The Voice UK.
He took to Instagram to show off the results of his weight loss after slimming down in seven weeks.
And how did he do it? In another post earlier this month, he opened up about a seven day juice cleanse he used:
"This week was truly incredible, we arrived Saturday at this retreat and had no idea what to expect but wow did it deliver.
“Surrounded by people all here on a journey ready to Juice cleanse and detox the body for 7days! Sounds crazy having no food for 7days but wow just wow! I feel amazing.."
He also posted videos/pics of him working out.
