Mariah Carey is kicking off her new world tour The Adventures of Mimi and showing off her new slim shape, which she claims is thanks to the "Morsel Diet".

The newly svelte star worked out with a fitness trainer and did water aerobics in addition to her new diet plan.

She explains, "I kind of invented it. Basically you can have a tiny bit of everything you want.

"When I'm really, really hungry I'll be like 'I need a morsel!'

"So they'll give just me whatever is there (on the plate), but it has to be less than a forkful."
