Kourtney Kardashian has stepped out looking hilariously unrecognisable

Kourtney Kardashian that you...?

Kourt has managed to completely baffle the streets of Los Angeles, going undercover as part of a skit for Jimmy Kimmel Live!.

The normally super glamorous mumma went to great lengths to make sure she wouldn’t be spotted – even sporting a platinum blonde wig and prosthetic nose for the stunt.

And, it seems that her disguise did just the trick, as she went undetected!
