Kim Kardashian gets a dramatic make-under for ‘Celebrities Undercover’

You’ve never seen Kim Kardashian like this before.

Appearing on Oxygen’s new reality show called Celebrities Undercover on Tuesday, Kanye West’s fiancé was rendered unrecognizable with the help of prosthetics, a frizzy wig, fake teeth and a pair of glasses.

The 33-year-old tricked fans into thinking they were interviewing to be Kim’s new assistant, while the star — who used the pseudonym "Cynthia" — quizzed the applicants’ loyalty.

Even sister Kourtney didn't recognize the brunette beauty until she ripped off the disguise and revealed her true self.

"I have something to tell you," she said during the big reveal. "You've been with Kim all day. You have been with me all day."

When the prank was all over, North West's famous mom gave each of her surprised fans a big hug.

Other celebrities who are slated to appear incognito on the show, which airs Tuesday nights at 10:30 p.m., include Fantasia, Lil Kim and Joey Fatone.
