Katy Perry's backstage rider demands have been revealed - and it seems she is a devotee of healthiness.

The singer regularly performs live around the world and TMZ have obtained her backstage rider list.

It sees a number of healthy options - such as vegetables, fruit and low-fat options - included, with a high importance placed on fresh food.

It reads: "Fresh vegetables AT ALL TIMES - including spinach/broccoli/celery/beets/carrots/kale, etc. Two large baskets of fruit - one must be tropical. Dinner must include a vegetarian option ... plus Quinoa or couscous. ALL meals must be low-fat and health conscious and cannot contain MSG."

Perry has another list for her own private dressing room, which includes items such as granola, tortilla chips and sliced organic fruit.

The US star meanwhile is due to bring her Prismatic tour to the UK this summer, with dates starting on May 7 in Belfast.
