Kim Kardashian has undergone a geeky makeover to disguise herself for an appearance on an undercover Tv show.

The reality star sports a brown, curly wig, false teeth, glasses and prosthetics on her face for a spot on Wendy Williams' new Tv show Celebrities Undercover, in which stars undergo a dramatic makeover to fool fans.

The brunette beauty adopted the persona of 'Cynthia' to interview three candidates who had applied for a job as an assistant on her Tv show Keeping Up With The Kardashians.
