KJ dropped her debut episode of "Cooking with Kylie" Monday morning ... which probably sounds very familiar to her bro Rob Kardashian, since his gf's been doing the same damn thing!
BC's been doing "Cooking with Chyna" on social media for a few months. In fact, Rob was a fan of the page even before he hooked up with Chyna.
Kylie's new venture didn't go over well. Minutes after her 'Cooking' announcement, Chyna posted this not-so-cryptic message: "Bitch Bye Follow @cookingwithchyna #InfatuatedWitChy."
They've got 9 months to sort out who cooks Thanksgiving dinner.
