Katy Perry will allegedly strip down to her smalls for the front cover of the UK edition of Rolling Stone magazine.

According to Monsters & Critics, the Firework singer will take part in a sexy photo shoot for the latest issue of the publication and pose in a blush two-piece lingerie set for the raunchy pictures.

Perry, who has previously graced the cover of the US version of Rolling Stone wearing underwear back in August 2010, is also said to have posed in just fishnet stockings for a seaside snap to be used inside the mag.

The Teenage Dream hitmaker told the publication that she has been on a strict diet in order to prepare for the saucy shoot and to keep fit for her 90 date California Dreams tour later this year.

The 25-year old claimed: “I’m on a meal plan, which absolutely sucks. But, on Sundays, I get to have a cheat day where I go buck wild and eat In-N-Out Burger,”

She added: “I’ll work out, go to a vocal lesson, run through the entire set at rehearsals, go to dance rehearsal until 10 p.m. and then go home and sort through e-mails concerning the production. I feel like I’m training for the Olympics.”

Katy, who married comedian Russell Brand last October, also told the magazine that getting hitched is not going to change the music she makes.

Perry, who is known for sexy songs such as I Kissed A Girl, explained: “There is an obvious element in me that wants to entertain people and make their faces light up. So I won’t only be singing songs about being a married woman.”

She added: “I always say a good example of that is Beyoncé. She sang Single Ladies but everyone knows she’s with Jay-Z.”
