Katy Perry in good shape for the cover of Rolling Stone

Nevertheless, in the picture showing her on the cover of Rolling Stone makes her look too slim, airbrushed.

The singer wears a pink bra and knickers with no hint of fat that results an impossibly thin body.

Moreover, we can analyze the airbrushed Katy Perry cover with the photo from the opening of Singfest music festival in Singapore from yesterday.

Katy held a press conference in a patterned bikini suit in a luxury infinity pool on the roof of Marina Bay hotel in the Sands Sky Park.

On the other hand, her trainer said: ‘She’s getting in shape for everything…wedding, music videos, touring, etc.

‘She works out as often as she can, she’s a busy woman but her goal is five times a week.’

‘She eats five small meals a day, each containing healthy fats, lean protein, fiber and a non-sugar drink.

‘A typical day’s diet would be an egg white omelet with a bowl of berries, an apple cinnamon smoothie, a chop salad, three-bean BBQ chips and finishing off with a seafood stir fry for dinner.’
