Katy Perry has posed semi-naked for a series of photos from her Moschino ad campaign.

The 'Roar' hitmaker was unveiled as the new face of the elite designer label - headed up by Jeremy Scott - last week when she posted the first shot from the upcoming campaign social media.

The 30-year-old singer has since posted six new pictures, including one where she flashes side-boob and side-butt, with a simple fur coat draped around her, gold shoes and a handbag.

Katy posted on Twitter: ''MORNING! For the next five hours I will post a new KATY x MOSCHINO picture through Instagram each hour, on the hour! (sic)''

The risque shot is one of a series taken for Moschino's autumn/winter collection for 2015 and received over 500,000 likes in under 24 hours.

The next one she posted yesterday morning (15.06.15) saw her wrap up in a purple jumper, a quilted backpack, oval-shaped sunglasses, two hats, again wearing very little on her bottom half, as she showed off her perfect pins while perching on a stool.

Another was reminiscent of her Met Gala Ball dress, the cropped black jacket featured white graffiti, gold chains and a matching handbag.

Katy still has her Kris Jenner-inspired pixie cut in each of images.

The pop superstar and designer have a strong connection ever since he designed her graffiti-styled dress for the Met Gala Ball.
