Don’t cross Kardashian matriarch Kris Jenner!

In a clip from the upcoming episode of Keeping Up With The Kardashians, the hot-headed momager completely flips when daughter Kim, 33, tricks her into walking through dog poop in the Jenner family laundry room.

“Kim! You piece of sh*t,” she screams as she steps into droppings left by daughter Kendall’s Great Dane Blu. “You’re an awful person, that you would let me walk into this as a joke…You’re not a good person.”

“It’s her responsibility!” counters Kim, adding that sis Kendall, 18, should place puppy Blu in a kennel when she’s gone for the weekend.

“You’re a pain in the [expletive], Kim,” snarls Kris. “You don’t even know how to help!”

“It is so gross, it’s like a It’s like 101 Dalmations pooped and peed in my laundry room times two,” the newly single mom, 58, adds.  “I really think my kids think that’s its my job to take care of them all, and I’m over it.”
