Demi Lovato has posed up a storm in a racy new photoshoot.

The Sorry Not Sorry singer has teamed with her photographer friend Angelo Kritikos for the images, which she unveiled on her Instagram page on Friday (15Sep17).

One snap, which shows her wearing a black leather Alexandre Vauthier top and skirt as well as black Christian Louboutin heels, racked up over one million 'likes' in a couple of hours.

Two other photos show Demi posing on a brown leather sofa and against a wall, with the 25-year-old showcasing her long black hair which had been styled with a slight wave.

The star unveiled four other snaps on Saturday, in which she is seen modeling a pair of boyfriend jeans, a denim bikini top, and a cropped jacket, while she has a bold swipe of pink eyeshadow swiped across her lids.

She simply captioned all of the pictures with a camera emoji and the photographer's Instagram handle, with followers commenting on how beautiful she looked in the photos.
