London, Jan 29 (Agencies): Singer Katy Perry, who is currently following a strict dieting regime has admitted her dislike towards going on a diet plan.

The "Firework" singer who is on a strict eating regime for the preparation of her album "Teenage Dreams Tour", revealed that she occasionally lets herself have "cheat days" where she allows herself a burger, according to media reports.

"I am on a meal plan, which absolutely sucks - but on Sundays I get to have a cheat day where I go wild and eat a burger," she said.

Katy, 26, also finds exercising in preparation for the world tour hard as thorough dance rehearsals make her feel as if she is in training for the Olympics.
