Katy Perry’s recent cover photo for Rolling Stone magazine has sparked controversy and accusations of Photoshop use.

The Daily Mail has pointed out that the photo, which shows the singer in a pink bra and underwear, appears to have had any body fat digitally removed and has been subject to standard smoothing and softening techniques.

This has led to criticism that the photo gives an unrealistic and potentially harmful portrayal of body image.

Despite the controversy, Katy Perry has been working hard to maintain her fitness and prepare for her upcoming wedding to comedian Russell Brand.

The singer has reportedly been exercising five times a week and following the “Five Factor Fitness” program, which includes a five-phase circuit and five small meals a day.

Celebrity trainer Harley Pasternak, who has worked with Perry, has described her goal as “to look amazing always” and stated that she is “getting in shape for everything… wedding, music videos, touring, etc.”

Pasternak added: ‘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.’

In addition to her fitness routine, Perry has also been seen showing off her curves at various public events.

One notable example was a press conference at a rooftop infinity pool in Singapore, where she wore a patterned bikini.

According to reports, the singer has even stepped up her workouts in the lead-up to her wedding and is determined to look her best for the big day.

Perry has also faced rumors about breast augmentation, although she has not confirmed or denied these reports.

In the Rolling Stone interview itself, Perry discussed a range of topics including her childhood and relationship with her parents.

She described them as “freelance” ministers who used to speak in tongues and had unusual rules about deviled eggs.

The singer also spoke about her current career and upcoming projects, including her upcoming wedding and new album.
