Britain’s Got Talent boss Simon Cowell has reportedly lost 12lbs on a strict detox diet, because he wants to be more svelte for his wedding to Mezhgan Hussainy.

The music mogul is reportedly surviving on smoothies and veggie shakes as well as one protein based meal in the evening. A pal told The Mirror:

“He insists they give him all the vitamins and minerals he needs. He believes they do him a world of good. He’ll certainly be in peak condition for the new Britain’s Got Talent next weekend.”

Simon is now said to weigh just 13 stone and has cut his cigarette intake down from 40 a day to just 15.
