Kris Jenner Got Really High With Her Mom [VIDEO]

In a preview for the “Keeping Up With The Kardashians” episode that airs Aug. 11, Kris Jenner and mother Mary Jo buy medical marijuana and get really high (complete with a huge bowl of chips and dip in front of them, of course), and cannot stop giggling, which really pisses off Bruce.

Oops, guess she forgot two teenagers live in the house.
