Kris Jenner and Kim Kardashian Pull a TV Bait and Switch

Kim Kardashian conspired with her mother by making it APPEAR the newly-minted mom would reveal her post-pregnant body on Kris Jenner's show today ... but it was all a ruse.

Kim tweeted, "Getting ready to surprise my mom on @krisjennershow today. You ready NYC? Tune in!"

Call us cynical, but it was no surprise to Kris when Kim did indeed appear ... but if you expected to see her body ... sorry suckers.

It was all a ploy to goose ratings ... kind of like when Kris made potential viewers believe she would debut North West.

BTW the best part ... Kris cries when she sees the video. Remember, Kim lives with her.
