A man claims he has gone to the extreme lengths of surgically removing his nipples and belly button, all in the name of art.

Karim Boumjimar, an 18-year-old Spanish-Moroccan artist, posted pictures of his lopped off body parts online, which he plans to sell them to the highest bidder.

The teenager, who is based in London, plans to turn the nipples into earrings and warned his Twitter followers that a 'belly button necklace' was coming soon.

He hopes to sell them for 'a big amount' and warned his Twitter followers that his 'belly button necklace' is coming soon

Karim, who has appeared in Zayn Malik's BeFoUr video, shared a photo of what looked like his pierced, unattached nipples along with a topless selfie - revealing his apparently nipple-less chest.

He claimed he used foundation to hide his scars.

The nipples are to be sold as earrings, for around £100, although the artist hopes to get more for them in order to make back the money he paid for surgery.

In an interview with Dazed, Karim revealed that the operation 'wasn't really done legally' and that he was given 'so many drugs'. He was then handed his nipples at the end of it.

In the future, Mr Boumjimar plans to travel to Bosnia 'to get more body alterations'.

One Twitter user accused him of lying, saying that the photo showing his cut off nipples was in fact of 'lemon ends', 'smh' being an abbreviation of 'shaking my head'

He told Dazed: '[I might get] something with my feet, like attach something to them', adding that cutting his tongue did not appeal to him.

Karim received a mixed reaction to his body modification on social media, with a number of his followers querying whether the pictures had been Photoshopped.

One Twitter user simply asked him: 'What the f*** is wrong with you?'.

Another accused him of lying, saying that the photo showing his cut off nipples was in fact 'lemon ends'.
