Kanye West has had his bottom teeth removed and replaced with diamonds.

The rapper unveiled his new dentures during an appearance on US chat show, The Ellen DeGeneres Show.

DeGeneres asked West if the diamonds were a removable grill, which snaps over the teeth, but the rapper insisted they were permanent.

"I just thought the diamonds were cooler,” West said. “There's just certain stuff that rock stars are supposed to do."

West was appearing on the chat show to promote his forthcoming fifth studio album 'My Beautiful Dark Twisted Fantasy', which is released on November 22.

Meanwhile, the rapper revealed that "there were times that I contemplated suicide”, but he refused to elaborate on when.
