Katy Perry is taking it all off for her new Moschino campaign.

After sharing her first ad for the eclectic high-fashion brand last week, in which she wore a quilted gold bra top that she's very questionably worn before, Katy shared a whole new set of fierce pics on Monday. In the most eye-catching image, the 30-year-old "Dark Horse" singer ditches her undies and shows a whole lot of side boob, wearing nothing but a Moschino robe and gold heels.

Clearly, Moschino's playful aesthetic is right up Katy's alley. Check her out modeling some straight-up '90s looks with her Kris Jenner-type 'do.

And here she is looking glam in a peplum graffiti gown, matching the wall beside her.

Katy has been a longtime pal of Moschino Creative Director Jeremy Scott, who accompanied her to this year's MET Gala -- where she donned Moschino of course.
