It's claimed to be the 'secret slimming weapon' keeping some of Britain's best-known reality TV stars trim and in shape.

Skinny Sprinkles is endorsed by a host of stars including Geordie Shore star Holly Hagan – who has dropped four dress sizes from a 16 to a eight.

Holly's fellow cast members Chloe Ferry and Sophie Kasaei – who have shed two stone and three stone respectively – have also credited the drink with their transformations.
